NatC N-alpha-acetyltransferase complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
N(alpha)-acetyltransferases, NatA (CPX-781), NatB (CPX-782) and NatC, carry out N-terminal acetylation, one of the most common co-translational modifications. Mak3 is the catalytic subunit of NatC. All three subunits are required for NatC activity. NatC substrates are rare but subclasses of proteins with Met-Ile, Met-Leu, Met-Trp, or Met-Phe termini are not acetylated in Mak3 deletion mutants. All three deletion strains showed similar phenotypes, including slower growth on non-fermentable carbon sources at elevated temperature.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
