Butirosin is an interesting 2-deoxystreptamine (DOS)-containing aminoglycoside antibiotic produced by non-actinomycete Bacilli. Recently we were successful in purification of 2-deoxy-scyllo-inosose synthase from butirosin-producer Bacillus circulans as the key enzyme for the biosynthesis of DOS, in cloning of the responsible gene
