EC 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.
