Recombinant proteins for sirtuin 5 are available from various sources. In humans, this protein has a Uniprot ID of Q9NXA8 and has an annotated function: 'NAD-dependent lysine demalonylase, desuccinylase and deglutarylase that specifically removes malonyl, succinyl and glutaryl groups on target proteins.' This protein is 310 amino acids in length and 33.9 kilodaltons in mass. It has been designated a subcellular localization as: cytoplasmic, nuclear, mitochondrial. This protein is encoded by the gene SIRT5. Other names also exist, such as: NAD-dependent protein deacylase sirtuin-5, mitochondrial, NAD-dependent deacetylase sirtuin-5, NAD-dependent lysine demalonylase and desuccinylase sirtuin-5, mitochondrial, silent mating type information regulation 2, S.cerevisiae, homolog 5, sir2-like 5, sirtuin type 5. As many as 4 isoforms have been named. This protein is conserved in other species, including: mouse, rat.
