1 Supplementary Material for Pacholec, M. et al. manuscript SRT1720, SRT2183, SRT1460, and resveratrol are not direct activators of SIRT1 Supplementary Figure Legends Figure S1. Determination of SIRT1 K m values for native p53 peptide and NAD +. The SIRT1 reactions were carried out at 5 nm SIRT1 under the conditions described under Experimental Procedures. For the K m value determinations of the native peptide, the peptide concentrations were varied from 0.78 to 100 M and NAD + was kept at 2 mm. For the K m value for NAD +, NAD + was varied from 0.5 to 1000 M and the native peptide was kept at 75 M. The data were fitted into the Michaelis Menten equation using KaleidaGraph. The K m and k cat values of 4.5 ± 0.17 M and 0.19 s -1 were obtained for the native peptide, respectively. The corresponding K m and k cat values for NAD + were 94 ± 5 M and 0.22 s -1. Figure S2. SDS-PAGE of purified p53. Purification of p53 using a Ni-NTA column followed by IEX Q Sepharose. Pools from each column were subjected to a 4-12% NuPage Bis-Tris SDS- PAGE under reducing conditions and stained with Coomassie Blue. lane 1-See Blue Plus 2 Markers; lane 2- pool from Ni-NTA (5 g); lane 3 pool from IEX Q Sepharose (1 g). Figure S3: SPR study on interaction of SRT1720 with p53-derived peptide substrates in the absence of SIRT1. Replicate injections of SRT1720 (2-fold dilutions at 3-50 M) passed over the surface of the TAMRA Peptide 1 (A) and the Native Peptide 1 (B). The amino acid sequence 1
2 of the TAMRA Peptide 1 and the Native Peptide 1 are identical and differ only in the TAMRA group (Table S1). 2
