Mechanism of aminoglycoside 3'-phosphotransferase type IIIa: His188 is not a phosphate-accepting residue

Abstract

BACKGROUND: The enzyme aminoglycoside 3'-phosphotransferase Type IIIa (APH(3')-IIIa), confers resistance to many aminoglycoside antibiotics by regiospecific phosphorylation of their hydroxyl groups. The chemical mechanism of phosphoryl transfer is unknown. Based on sequence homology, it has been suggested that a conserved His residue, His188, could be phosphorylated by ATP, and this phospho-His would transfer the phosphate to the incoming …
