IntEnz Enzyme Nomenclature


Accepted name:
aminoglycoside N3-acetyltransferase
Other names:
3'-aminoglycoside acetyltransferase
3-N-aminoglycoside acetyltransferase
aminoglycoside 3-N-acetyltransferase
3-aminoglycoside acetyltransferase
acetyl-CoA:2-deoxystreptamine-antibiotic N3'-acetyltransferase [incorrect]
aminoglycoside N3'-acetyltransferase [incorrect]
Systematic name:
acetyl-CoA:2-deoxystreptamine-antibiotic N3-acetyltransferase



Different from EC gentamicin N3-acetyltransferase. A wide range of antibiotics containing the 2-deoxystreptamine ring can act as acceptors, including gentamicin, kanamycin, tobramycin, neomycin and apramycin.
