IUBMB Enzyme Nomenclature


Accepted name: capreomycidine synthase

Reaction: (2S,3S)-3-hydroxyarginine = (2S,3R)-capreomycidine + H2O

Glossary: (2S,3R)-capreomycidine = (S)-2-amino-2-[(R)-2-iminohexahydropyrimidin-4-yl]acetic acid

Other name(s): VioD (ambiguous)

Systematic name: (2S,3S)-3-hydroxyarginine hydro-lyase (cyclizing, (2S,3R)-capreomycidine-forming)

Comments: A pyridoxal 5'-phosphate protein. The enzyme is involved in the biosynthesis of the cyclic pentapeptide antibiotic viomycin.
