KEGG ENZYME: 2.7.7.46

ENZYME: 2.7.7.46

Entry

EC 2.7.7.46 Enzyme

Name

gentamicin 2''-nucleotidyltransferase;
gentamicin 2''-adenylyltransferase;
aminoglycoside adenylyltransferase;
gentamycin 2''-nucleotidyltransferase

Class

Transferases;
Transferring phosphorus-containing groups;
Nucleotidyltransferases

Sysname

NTP:gentamicin 2''-nucleotidyltransferase

Reaction(IUBMB)

nucleoside triphosphate + gentamicin = diphosphate + 2''-nucleotidylgentamicin [RN:R02432]

Reaction(KEGG)

R02432 > R09047

Substrate

nucleoside triphosphate [CPD:C00201];
gentamicin [CPD:C00505]

Product

diphosphate [CPD:C00013];
2''-nucleotidylgentamicin [CPD:C03565]

Comment

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.
