N-terminal acetylation (NTA) (see Glossary) is one of the most widespread protein modifications, which occurs on most eukaryotic proteins, but is significantly less common on bacterial and archaea proteins. This modification is carried out by a family of enzymes called N-terminal acetyltransferases (NATs) (see Glossary). To date, twelve NATs have been identified, harboring different composition, substrate specificity and, in some cases, modes of regulation. Recent structural and biochemical analysis of NAT proteins now allows for a comparison of their molecular mechanisms and modes of regulation, which are described here. Although sharing an evolutionarily conserved fold and related catalytic mechanism, each catalytic subunit employs unique elements to mediate substrate-specific activity and employ NAT-type specific auxiliary and regulatory subunits for their cellular functions.
