EC 1.14.19.61     
Accepted name: dihydrorhizobitoxine desaturase
Reaction: dihydrorhizobitoxine + 2 reduced ferredoxin [iron-sulfur] cluster + O2 + 2 H+ = rhizobitoxine + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H2O
Glossary: dihydrorhizobitoxine = (2S)-2-amino-4-[(2R)-2-amino-3-hydroxypropoxy]butanoate
rhizobitoxine = (2S,3E)-2-amino-4-[(2R)-2-amino-3-hydroxypropoxy]but-3-enoate
Other name(s): rtxC (gene name)
Systematic name: dihydrorhizobitoxine,ferredoxin:oxygen oxidoreductase (3,4 trans-dehydrogenating)
Comments: The enzyme, characterized from the bacterium Bradyrhizobium elkanii, catalyses the final step in the biosynthesis of the nodulation enhancer compound rhizobitoxine.
