Protein

NAD-dependent protein deacetylase HST2

Gene
HST2, YPL015C, LPA2C
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

NAD-dependent histone deacetylase that is involved in nuclear silencing events. Derepresses subtelomeric silencing and increases repression in nucleolar (rDNA) silencing. Its function is negatively regulated by active nuclear export.5 Publications

Catalytic activityi

NAD+ + an acetylprotein = nicotinamide + O-acetyl-ADP-ribose + a protein.1 Publication

Cofactori

Binds 1 zinc ion per subunit.

Enzyme regulationi

Inhibited by ADP-ribose and nicotinamide.1 Publication

Kineticsi

  1. KM=10.2 µM for NAD+4 Publications
  2. KM=0.92 µM for acetylated poly-L-lysine
  3. KM=0.5 µM for a synthetic histone H3K14 acetyllysine peptide
