Glycosyltransferase involved in the biosynthesis of butirosin by mediating conversion of 2-deoxystreptamine (2-DOS) to 2'-N-acetylparomamine using UDP-alpha-D-glucosamine as sugar donor. 2-deoxystreptamine + UDP-N-acetyl-alpha-D-glucosamine = 2'-N-acetylparomamine + H(+) + UDP Antibiotic biosynthesis; butirosin biosynthesis. In contrast to KanF enzyme in S.kanamyceticus, can only accept UDP-N-acetyl-alpha-D-glucosamine and not UDP-alpha-D-glucose. Belongs to the glycosyltransferase group 1 family.
