Function

SIR2_HUMAN NAD-dependent protein deacetylase, which deacetylates internal lysines on histone and non-histone proteins. Deacetylates 'Lys-40' of alpha-tubulin. Involved in the control of mitotic exit in the cell cycle, probably via its role in the regulation of cytoskeleton. Deacetylates PCK1, opposing proteasomal degradation. Deacetylates 'Lys-310' of RELA.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

SIRT2 deacetylates specific acetyllysine residues in diverse proteins and is implicated in a variety of cellular processes. SIRT2 inhibition thus has potentials to treat human diseases such as cancers and neurodegenerative disorders. We have recently developed a series of epsilon-trifluoroacetyllysine-containing macrocyclic peptides, which inhibit the SIRT2 activity more potently than most other known inhibitors. Here, we report the crystal structure of human SIRT2 in complex with a macrocyclic peptide inhibitor, S2iL5, at 2.5 A resolution. The structure revealed that S2iL5 binds to the active site of SIRT2 through extensive interactions. A structural comparison of the SIRT2-S2iL5 complex with SIRT2 in the free form, and in complex with ADP-ribose, revealed that S2iL5 induces an open-to-closed domain movement and an unexpected helix-to-coil transition in a SIRT2-specific region. Our findings unveil the potential of macrocyclic peptides to bind target proteins by inducing dynamic structural changes.
