== Function ==
[https://www.uniprot.org/uniprot/SIR3_HUMAN SIR3_HUMAN] NAD-dependent protein deacetylase. Activates mitochondrial target proteins, including ACSS1, IDH2 and GDH by deacetylating key lysine residues. Contributes to the regulation of the cellular energy metabolism. Important for regulating tissue-specific ATP levels.<ref>PMID:16788062</ref> <ref>PMID:18680753</ref> <ref>PMID:18794531</ref> <ref>PMID:19535340</ref>

== Publication Abstract from PubMed ==
Two new analogs of halistanol sulfate (1) were isolated from a marine sponge Halichondria sp. collected at Hachijo-jima Island. Structures of these new halistanol sulfates I (2) and J (3) were elucidated by spectral analyses. Compounds 1-3 showed inhibitory activity against SIRT 1-3 with IC50 ranges of 45.9-67.9, 18.9-21.1 and 21.8-37.5 muM, respectively. X-ray crystallography of the halistanol sulfate (1) and SIRT3 complex clearly indicates that 1 binds to the exosite of SIRT3 that we have discovered in this study.
