N-terminal (Nt)-acylation is the irreversible addition of an acyl moiety to the terminal alpha amino group of a peptide chain. This type of modification alters the nature of the N terminus, which can interfere with the function of the modified protein by disrupting protein interactions, function, localization, degradation, hydrophobicity, or charge. Nt acylation is found in all domains of life and is a highly common occurrence in eukaryotic cells. However, in prokaryotes very few cases of Nt acylation have been reported. It was once thought that Nt acylation of proteins, other than ribosomal proteins, was uncommon in prokaryotes, but recent evidence suggests that this modification may be more common than once realized. In this review, we discuss what is known about prokaryotic Nt acetylation and the acetyltransferases that are responsible, as well as recent advancements in this field and currently used methods to study Nt acetylation.
