Contents

Sir2 bound to acetylated peptide

Template:ABSTRACT PUBMED 19801667

Function

[NPD_THEMA] NAD-dependent protein deacetylase which modulates the activities of several enzymes which are inactive in their acetylated form. Has also depropionylation activity in vitro. Also able to ADP-ribosylate peptide substrates with Arg or Lys in the +2 position. The role of this function in vivo is not clear.[1] [2] [3]
