Other name(s): btrN (gene name); 2-deoxy-scyllo-inosamine dehydrogenase (SAM-dependent)
Systematic name: 2-deoxy-scyllo-inosamine:S-adenosyl-L-methionine 1-oxidoreductase
Comments: Involved in the biosynthetic pathway of the aminoglycoside antibiotics of the butirosin family. The enzyme from Bacillus circulans was shown to be a radical S-adenosyl-L-methionine (SAM) enzyme. cf. EC, 2-deoxy-scyllo-inosamine dehydrogenase.
