AatD
AatD is an enzyme found in certain Gram-negative bacteria, where it functions as an N-acyltransferase within the Aat secretion system. It is most closely associated with pathogenic strains of Escherichia coli that produce the heat-stable enterotoxin STa and other small secreted peptides.
The primary role of AatD is to catalyze the N-acylation of exported peptides, most notably the precursor
Genetically, AatD is encoded in the aat gene region alongside other components of the Aat secretion system.
Understanding AatD has implications for studying bacterial secretion systems and for exploring potential therapeutic approaches aimed
