Protein

N-terminal acetyltransferase A complex catalytic subunit ARD1

Gene

ARD1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalytic component of the NatA N-terminal acetyltransferase, which catalyzes acetylation of proteins beginning with Met-Ser, Met-Gly and Met-Ala. N-acetylation plays a role in normal eukaryotic translation and processing, protect against proteolytic degradation and protein turnover.2 Publications

Miscellaneous

Present with 3310 molecules/cell in log phase SD medium.1 Publication
