dicyanocobinamide salvage pathway Dicyanocobinamide is a coenzyme B<sub>12</sub> precursor. Regarding Woodson ate al [PMID:14990804] prokaryotes have evolved at least two distinct pathways for salvaging the precursor cobinamide (Cbi) from the environment. Both pathways accomplish the same goal, which is to convert AdoCbi (adenosylcobinamide) to AdoCbi-P, a true intermediate of the de novo biosynthetic pathway.
