Accepted name: 2-deoxystreptamine N-acetyl-D-glucosaminyltransferase
Reaction: UDP-N-acetyl-α-D-glucosamine + 2-deoxystreptamine = UDP + 2′-N-acetylparomamine

Other name(s): btrM (gene name); neoD (gene name); kanF (gene name)
Systematic name: UDP-N-acetyl-α-D-glucosamine:2-deoxystreptamine N-acetyl-D-glucosaminyltransferase
Comments: Involved in the biosynthetic pathways of several clinically important aminocyclitol antibiotics, including kanamycin, butirosin, neomycin and ribostamycin. Unlike the enzyme from the bacterium Streptomyces kanamyceticus, which can also accept UDP-D-glucose [2] (cf. EC, 2-deoxystreptamine glucosyltransferase), the enzyme from Bacillus circulans can only accept UDP-N-acetyl-α-D-glucosamine [1].
