Aminoglycoside 6'-N-acetyltransferase.
based on mapping to UniProt Q6SJ71
Acetyl-CoA + kanamycin-B = CoA + N(6')-acetylkanamycin-B.
-!- The antibiotics kanamycin A, kanamycin B, neomycin, gentamicin C(1a), gentamicin C(2), sisomicin and tobramycin are substrates. -!- The antibiotic paromomycin is not a substrate. -!- The 6-amino group of the purpurosamine ring is acetylated. -!- Formerly EC 2.3.1.55.
