2.3.1.82 |
| Accepted name: |
aminoglycoside 6′-N-acetyltransferase |
| Reaction: |
acetyl-CoA + kanamycin-B = CoA + N6′-acetylkanamycin-B |
| Glossary: |
kanamycin |
| Other name(s): |
aminoglycoside N6′-acetyltransferase; aminoglycoside-6′-acetyltransferase; aminoglycoside-6-N-acetyltransferase; kanamycin acetyltransferase |
| Systematic name: |
acetyl-CoA:kanamycin-B N6′-acetyltransferase |
| Comments: |
The antibiotics kanamycin A, kanamycin B, neomycin, gentamicin C1a, gentamicin C2 and sisomicin are substrates. The antibiotic tobramycin, but not paromomycin, can also act as acceptor. The 6-amino group of the purpurosamine ring is acetylated. |
