Cobamide biosynthesis

The gut microbiome is a complex community whose stability requires metabolic interactions between microbes, including cross-feeding of nutrients like cobamides. Cobamides are a family of organometallic co-factors including vitamin B12, which supports metabolism in all three domains of life.

Regiospecific Formation of Cobamide Isomers Is Directed by CobT

Biochemistry, 2014
Cobamides, which include vitamin B₁₂ (cobalamin), are a class of modified tetrapyrroles synthesized exclusively by prokaryotes that function as cofactors for diverse biological processes. Cobamides contain a centrally bound cobalt ion that coordinates to upper and lower axial ligands.

[211] Processes for the biosynthesis of cobamides

1971
Publisher Summary This chapter discusses several processes for the biosynthesis of cobamides. Three types of processes have been described in the literature. First, cobamide-producing cultures are grown in cobalt salt-containing media, the cells are harvested, and the cobamide is recovered by extraction from the cells.
