Background: Sirtuin 5/SIRT5

Sirtuin 5, encoded by the SIRT5 gene, is a nicotinamide adenine dinucleotide (NAD)-dependent enzyme that is part of the SIRT family also known as the SIR2 (silent information regulator 2)-like protein family.  The SIR2 family of enzymes is classified as class III histone deacetylases (HDACs). The family is comprised of seven family members, SIRT1-7 that contain the conserved NAD-binding and catalytic domains but have distinct N- and C-termini that contribute differences in specificity, subcellular localization and enzymatic activity (1,2). SIRT5 is a 310 amino acid protein with broad tissue distribution (3,4) and primarily localized to the mitochondrial matrix (3,4) with a larger acyl binding pocket and unique active site residues compared to other SIRTs (1,2). SIRT5 possesses very weak deacetylase activity but can perform protein desuccinylation, demalonylation, and deglutarylation (1,2) due to its altered binding pocket. It is the principal regulator of these modifications in mitochondrial as well as the cytosolic and nuclear proteins based on proteomic detection of hundreds of SIRT5 substrate molecules (5-9). SIRT5 is implicated to impact cellular processes including metabolism (9-11) and fatty acid B-oxidation (6,11,12) in maintenance of cardiac homeostasis (12,13), cancer (14-16), and neurodegenerative disorders (17,18). Given its role in many pathologies, there is significant interest in targeting SIRT5 therapeutically (11,16).
