Background: Sirtuin 5/SIRT5

Sirtuin 5 (SIRT5; SIR2-like protein 5) is a 28‑35 kDa class III member of the sirtuin protein family. It is found in the mitochondrial matrix and is involved in ammonia detoxification. In particular, it deacetylates carbamoyl phosphate synthetase 1/CPS1, thus activating it and allowing for ammonia condensation with bicarbonate and ATP. This is a crucial step in urea formation during prolonged fasting or the use of a high-protein diet. Human SIRT5 is 310 amino acids (aa) in length. It possesses a sertuin‑type deacetylase domain (aa 41‑309) that contains an NAD binding motif (Thr276:Glu277:Pro292). There are three potential isoform variants that show aa substitutions at the C‑terminus. One contains a 14 aa substitution for aa 286‑310, a second shows a 15 aa substitution for aa 287‑310, and the third shows a 17 aa substitution for aa 207‑310. Full-length human and mouse SIRT5 share 86% aa identity.
