Figure 1
Enzymatic function of sirtuins. (A) NAD-dependent protein lysine deacylation activity of different sirtuins. (B) Enzymatic reaction mechanism of sirtuins. (C) Structure of a ternary sirtuin-NAD-acetyl peptide complex (PDB ID 2H4F). NAD, acetyl lysine, and the key catalytic His residue are shown in stick representation. Bound zinc is shown as a gray sphere. Protein structure picture is generated using PyMol.
