WebKanamycin kinase. Aminoglycoside-3'-phosphotransferase (APH (3')), also known as aminoglycoside kinase, is an enzyme that primarily catalyzes the addition of phosphate from ATP to the 3'-hydroxyl group of a 4,6-disubstituted aminoglycoside, such as kanamycin. [2] However, APH (3') has also been found to phosphorylate at the 5'-hydroxyl group in ... Web17 Feb 2024 · In mammals, nucleoside diphosphate kinase (NDPK, or NDK) is a ubiquitous enzyme that catalyzes the conversion of nucleoside diphosphates (NDPs) into nucleoside triphosphates (NTPs) by transferring terminal γ-phosphate groups from 5′-triphosphate-nucleotides to 5′-diphosphate-nucleotides.
