1 Supplementary Figure 1 RNAseq expression profiling of selected glycosyltransferase genes in CHO. RNAseq analysis was performed on two common CHO lines (CHO-K1, CHO-GS) and two independent CHO-GS triple mgat4a/4b/5 KO clones (ZFN91-1C8, ZFN91-2A6). The reported RNAseq analysis of CHO-K1 1 is included, and this was largely identical to our analyses except that the relative expression levels were higher. Importantly, a few genes including mgat4b reported not to be expressed in CHO-K1, were found in the present study to be expressed, and in the case of mgat4b this gene was found to be relevant for engineering loss of triantennary N-glycan branching (Fig. 1b). Another important observation was that the expression profiles of glycogenes in the two triple KO clones analysed were identical to those of the parental CHO lines, providing evidence that the gene editing did not alter expression of other glycogenes, although RNAseq data for all mutant clones are required for complete evaluation.

2 Supplementary Figure 2 N-glycan analysis by exoglycosidase treatment. Sialic acid and galactose residues of native N-glycans were sequentially removed by chemical (2% formic acid (v/v), 80 C, 2h) and enzymatic (E. coli βgalactosidase) treatment. Permethylated N-glycans from EPO produced in mgat4a/4b/5 KO CHO cells before (a) and after (b) desialylation/degalactosylation. The major peak detected after treatment (m/z ) (b) corresponds to a fucosylated biantennary N-glycan lacking sialic acids and galactose residues. The minor peak at m/z in (a) also shifts to m/z after the treatment (b), suggesting that one galactose residue is shielded by a terminal N-acetylglucosamine, which is in agreement with a LacNAc extension 2,3. Permethylated N-glycans from EPO produced in B3gnt2 KO CHO cells before (c) and after (d) desialylation/degalactosylation. The two major peaks at m/z and m/z (d) correspond to fucosylated tri- and tetraantennary N-glycans lacking sialic acid and galactose residues. In this genetic background (B3gnt2 KO), the peak at m/z (c) shifts to m/z (d), demonstrating that all galactose residues were exposed to the β-galactosidase enzyme which is in agreement with a triantennary N-glycan structure. The peaks at m/z and m/z (d) could theoretically be LacNAc extensions on triantennary N-glycans, but are most likely due to incomplete β-galactosidase digestion in agreement with the genetic background.

3 Supplementary Figure 3 Analysis of O-glycosylation of EPO expressed in CHO KO clones. The single O-glycan in human EPO at S126 was analysed from tryptic digests of EPO expressed in CHO WT and CHO with six stacked glycogene KO (B3gnt2/st3gal4/6/mgat4A/4B/5) monitoring the EAISPPDAASAAPLR131 glycopeptide. We used isotopomeric dimethyl labeling 4 for relative quantification of the glycosite occupancy and glycan structure. CHO WT and KO EPO tryptic digest samples were labelled with light (L) and medium (M), respectively, and quantification of peak areas of the extracted ion chromatogram (XIC) for the unglycosylated peptide and the glycopeptides with different glycoforms were presented as a bar chart. EPO tryptic peptides from WT and KO samples were loaded on in-house made equilibrated Stage Tip columns followed by by 3 x CV 0.1% FA wash. Digests were labeled on-column by adding 5 CV 30 mm NaBH3CN and 0.2% formaldehyde in 50 mm sodium phosphate buffer ph 7.5 (L-labeling) or 30 mm NaBH3CN and 0.2% D-formaldehyde in 50 mm sodium phosphate buffer ph 7.5 (M-labeling). Columns were washed using 3 CV 0.1% FA and eluted with 0.5 ml 50% MeOH in 0.1% FA. Samples were dried, reconstituted in 0. 1% FA and analyzed by EASYnLC 1000 UHPLC (Thermo Scientific) interfaced via nanospray Flex ion source to an LTQ-Orbitrap Velos Pro spectrometer (Thermo Scientific).

4 Supplementary Figure 4 SDS-PAGE Coomassie analysis of purified recombinant EPO and IgG. Approximately 1 µg of purified EPO (a), and 10 µl of culture supernatant of CHO clones producing high levels of IgG (b) were loaded to each lane.

5 Supplementary Figure 5 Growth characterization of CHO KO clones. (a) Growth and productivity analysis of CHO WT and two KO clones producing EPO. Cells were cultured in CO2 shaker in 30 ml of growth media in 50 ml TPP TubeSpin Bioreactors with 200rpm or 100ml in Corning 500ml culture bottle with 130rpm (Infors, USA). Cell density and viability were measured by trypan blue and productivity characterized by ELISA. Cells were seeded at 0.3x106 cell/ml, cultured for 5 days in fed-batch with additional 10% of feed containing 3% glucose supplied at day 3. Samples for glycan profiling were collected day 5. (b) Growth and productivity analysis of CHO WT and KO clones producing high levels of IgG (1 g/l). The B4galt1/fut8 KO was performed directly on the IgG producing CHO clone, and the KO clone maintained high productivity (g/l) as the WT. Growth of clones and productivity of EPO and IgG were not substantially affected by the glycogene KO. In general most of the CHO KO clones produced EPO yields comparable to WT cells (Supplementary Table 4). Based on purified yields the average yield of all CHO KO clones were 1.8 +/- 1.5 mg/l, and only 3 out of 21 of the initial KO cell lines produced low yields (22-44% of WT). This is remarkable since selection of stacked KO/KI CHO clones as well as EPO (and IgG) transfectants were based on a limited screen without focus on production yields. Thus, it is expected that careful selection of both stacked KO/KI CHO clones as well as screening for high producers will greatly improve yields, demonstrated in panel (b).

6 Supplementary Figure 6 Immunocytology of CHO KO clones for N-glycan branching and poly-lacnac biosynthesis. (a) The L-PHA lectin was used to specifically probe β6-branching of N-glycans and only KO of mgat5 produced (mgat4a/4b/5) altered Phytohemagglutinin-L lectin (L-PHA) labeling, while the control lectin Concanavalin A lectin (ConA) that binds to all types of N-glycans was unaffected. This confirms that MGAT4A and 4B forms the β4-branch, while MGAT5 forms the β6-branch, and hence supports the interpretation of the mass spec data presented in Figure 1b regarding branch assignments. (b) A similar strategy was used to probe for poly-lacnac with Lycopersicon esculentum lectin (LEL), where only KO of B3gnt2 resulted in loss of labeling. This data also support the interpretation of the mass spec data presented in Figure 2 regarding assignment of HexHexNAc units to poly-lacnac biantennary structures.

7 Supplementary Figure 7 Immunocytology of CHO KO clones with mutations related to LacNAc formation. (a) The monoclonal antibody 1B2 was used to label presence of LacNAc after removal of sialic acid by neuraminidase pretreatment. Analysis of KO of B4galt1-4 in CHO-GS WT with heterogeneous branching showed that KO of B4galt1 reduced labeling, while only stacked KO of B4galt1/3 completely abolished labeling. (b) The same analysis of KO of B4galt1-4 in CHO-GS engineered with homogenous biantennary N-glycans (KO of mgat4a/4b/5) showed that KO of B4galt1 alone essentially abolished MAb 1B2 labeling, indicating that β4gal-t1 is the main enzyme responsible for galactosylation of biantennary N-glycans. This finding is expected to have implications for recombinant production of therapeutic IgGs in CHO, since these proteins in general are produced with biantennary N- glycans with limited galactosylation 5.

8 Supplementary Figure 8 Immunocytology of CHO KO and KI clones related to sialylation. (a) The antibody 1B2 was used to label exposure of LacNAc as a result of loss of sialylation capacity, and this demonstrated that KO of st3gal3 and st3gal6 did not affect labeling substantially, while KO of st3galt4 and stacked KO of st3galt4/6 resulted in strong labeling. This suggests that the ST3Gal-IV enzyme is the main sialyltransferase responsible for α2,3sialylation of N-glycans. Furthermore, de novo introduction of human ST6Gal-I in the stacked st3galt4/6 KO clone completely abolished MAb 1B2 labeling demonstrating efficient sialylation by this enzyme. (b) To confirm the de novo introduction of human ST6Gal-I resulted in α2,6sialylation we used the Sambucus nigra lectin (SNA), which did not label CHO WT cells as expected and only labeled after introduction of ST6Gal-I.

9 Supplementary Figure 9 Analysis of targeted KI of ST6Gal-I by junction PCR. (a) We used a modified ObLiGaRe targeted KI strategy 6 utilizing two inverted ZFN binding sites flanking the ST6Gal-I full open reading frame in donor plasmid. 5 and 3 junction PCR confirmed targeted integration into the Safeharbor#1 site in the CHO clone with st3gal4/6 KO. (b) 5 and 3 junction PCR confirmed targeted integration in the CHO clone with st3gal4/6/mgat4a/4b/5 KO. The status of allelic copy number of integration was determined by WT allelic PCR. The presence of desired band in WT allelic PCR indicates the presence of Safeharbor#1 site without the integration of targeted KI of gene of interest on at least one of the allele. The results showed biallelic integration of ST6Gal-I at Safeharbor#1 site in the CHO-GS st3gal4/6 KO clone and monoallelic integration in the mgat4a/4b/5/st3gal4/6 KO clone.

10 Supplementary Figure 10 Negative ion ESI-MS glycoprofiling of EPO. Glycoprofiling of EPO produced in CHO WT, B3gnt2/mgat4A/4B/5, and st3gal4/6/mgat4a/4b/5 KO with KI of ST6Gal-I, showing complete loss of poly-lacnac on biantennary N-glycans, and complete de novo capping by α2,6 sialic acid on biantennary N-glycans without poly-lacnac. Negative ion ESI-MS glycoprofiling was used to validate MALDI-TOF based glycan profiling data.

11 Supplementary Figure 11 Negative ion ESI-MS/MS. Negative ion ESI-MS/MS of the precursor ions at m/z (sialylated biantennary N-glycan with core fucose) from EPO produced in CHO with mgat4a/4b/5 KO (top panels) and with both mgat4a/4b/5 and st3gal4/6 KO and KI of ST6Gal-I (bottom panels). The presence of the diagnostic fragment ions at m/z , 8 indicates α2,6 terminal sialylation.

12 Supplementary Figure 12 Graphic depiction of the genetic deconstruction of N-glycosylation in CHO established using EPO as N-glycoprotein reporter. The KO screen performed identifies the key glycogenes that control decisive steps in N-glycosylation of proteins in CHO and provides a matrix for genetic deconstruction of N-glycosylation capacity as well as a platform for reconstruction of desirable more homogeneous glycosylation capacities. The deconstruction provides engineering designs for CHO cells with capacity for production of EPO with for example homogeneous biantennary N-glycans capped with α2,3-linked. Two examples of reconstruction based on KI are shown producing homogeneous α2,6-sialylation after KO of α2,3-sialylation capacities with either WT N-glycan branching heterogeneity or homogeneous biantennary structure. We engineered capacity for homogenous N-glycans with and without core Fuc on IgG1 antibodies. Moreover, we engineered CHO cells with capacity for production of homogeneous monoantennary N-glycans, which are useful for direct GlycoPEGylation with a single modification per N-glycan. Several KO CHO lines have potential for production of glycoprotein therapeutics with more homogeneous glycosylation (e.g. biantennary α2,3-sialylated N-glycans for EPO, and biantennary non-galactosylated/sialylated with and without core Fuc for IgG). Reconstruction may address homogeneity as shown, but also branching, poly-lacnac elongation, and any type of capping as indicated. KO of mgat1 and fut8 were reported previously 9-11.
