Abstract

Background: Gcn5-related N-acetyltransferases (GNATs) are involved in small molecule and protein acetylation in all organisms. Results: Crystallographic and biochemical characterization of PA4794 is shown, including identification of substrates and inhibitors. Conclusion: PA4794 is a new bacterial C-terminal lysine protein acetyltransferase inhibited by cephalosporins. Significance: PA4794 is the first identified acetyltransferase specific for C-terminal lysine; identified interactions with cephalosporins may be of clinical relevance.
