Contrary to the accepted dogma that ATP is the canonical phosphate donor in aminoglycoside kinases and protein kinases, it was recently demonstrated that all members of the bacterial aminoglycoside 2''-phosphotransferase IIIa (APH(2'')) aminoglycoside kinase family are unique in their ability to utilize GTP as a cofactor for antibiotic modification ...
