PNC1

nicotinamidase, YGL037C
Nicotinamidase that converts nicotinamide to nicotinic acid; part of the NAD(+) salvage pathway; required for life span extension by calorie restriction; PNC1 expression responds to all known stimuli that extend replicative life span; protein increases in abundance and relative distribution to cytoplasmic foci decreases upon DNA replication stress

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Isonicotinamide enhances Sir2-mediated silencing and longevity in yeast by raising the intracellular NAD+ concentration.

McClure JM, Wierman MB, Maqani N, Smith JS

Sirtuins are an evolutionarily conserved family of NAD(+)-dependent protein deacetylases that function in the regulation of gene transcription, cellular metabolism, and aging. Their activity requires the maintenance of an adequate intracellular NAD(+) concentration through the combined action of NAD(+) biosynthesis and salvage pathways. Nicotinamide (NAM) is a key NAD(+) precursor that is also a byproduct and feedback inhibitor of the ... [more]
