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. |
