== Function == | |||
[[http://www.uniprot.org/uniprot/PNC1_YEAST PNC1_YEAST]] Catalyzes the deamidation of nicotinamide, an early step in the NAD(+) salvage pathway. Positively regulates SIR2-mediated silencing and longevity by preventing the accumulation of intracellular nicotinamide, an inhibitor of SIR2, during times of stress. Acts also on nicotinyl hydroxamate.<ref>PMID:11816029</ref> <ref>PMID:12736687</ref> <ref>PMID:14729974</ref> | |||
