Secondary Accession Numbers Not Available
Name NAD-dependent protein deacylase sirtuin-5, mitochondrial
Description Not Available
Synonyms
  1. SIR2-like protein 5
  2. Regulatory protein SIR2 homolog 5
Gene Name SIRT5
Protein Type Enzyme
Biological Properties
General Function Involved in zinc ion binding
Specific Function NAD-dependent lysine demalonylase and desuccinylase that specifically removes malonyl and succinyl groups on target proteins. Activates CPS1 and contributes to the regulation of blood ammonia levels during prolonged fasting: acts by mediating desuccinylation of CPS1, thereby increasing CPS1 activity in response to elevated NAD levels during fasting. Has weak NAD-dependent protein deacetylase activity; however this activity may not be physiologically relevant in vivo. Can deacetylate cytochrome c (CYCS) and a number of other proteins in vitro.
