EC 2.7.7.46     
Accepted name: gentamicin 2′′-nucleotidyltransferase
Reaction: nucleoside triphosphate + gentamicin = diphosphate + 2′′-nucleotidylgentamicin
Other name(s): gentamicin 2′′-adenylyltransferase; aminoglycoside adenylyltransferase; gentamycin 2′′-nucleotidyltransferase
Systematic name: NTP:gentamicin 2′′-nucleotidyltransferase
Comments: ATP, dATP, CTP, ITP and GTP can act as donors; kanamycin, tobramycin and sisomicin can also act as acceptors. The nucleotidyl residue is transferred to the 2-hydroxy of the 3-amino-3-deoxy-D-glucose moiety in the antibiotic.
