ENZYME entry: EC 5.4.99.61

Accepted Name
Precorrin-8X methylmutase.
Alternative Name(s)
HBA synthase.
Hydrogenobyrinic acid-binding protein.
Precorrin isomerase.
Reaction catalysed
Precorrin-8X <=> hydrogenobyrinate
Comment(s)
  • The enzyme catalyzes the the conversion of precorrin-8X to hydrogenobyrinate by methyl rearrangement, a step in the aerobic (late cobalt insertion) pathway of adenosylcobalamin biosynthesis.
  • The equivalent enzyme in the anaerobic pathway is EC 5.4.99.60.
  • Formerly EC 5.4.1.2.
