FIG. 1.
Structure of AdoCbl, aka coenzyme B12. The indicated gene functions involved in the synthesis of different parts of AdoCbl are those found in serovar Typhimurium. AdoCba's differ in their structures by the nature of the lower-ligand base (reviewed in reference 44). (A) Cbi, synthesized by CbiABCDETFGHJKLMNQOP. (B) Cobyric acid, synthesized by CbiACDETFGHJKLMNQOP. (C) 1-Aminopropanol-_O_-2-phosphate, synthesized by CobD. (D) Nucleotide loop, assembled by CobUTSC. Me, methyl; FMN, flavin mononucleotide.
FIG. 2.
The late steps of AdoCbl biosynthesis in bacteria and archaea. Shown in black boxes are archaeal enzymes that are nonorthologous replacements of the indicated bacterial enzyme. Abbreviations: Pi, orthophosphate; Na, nicotinate; Nm, nicotinamide; AdoCbl-P, AdoCbl-5′-phosphate.
