menaquinone biosynthesis via SEPHCHC~Menaquinone (also known as Vitamin K2) is one of the quinone cofactors which play an essential role in hydrogen transfer reactions, particularly during anaerobic respiration. Menaquinone in E. coli and various other bacteria is synthesized from chorismate, 2-oxoglutarate, polyprenyl-pyrophosphate and S-adenosylmethionine. A very similar molecule (phylloquinone, vitamin K1) is found in cyanobacteria and plants which contains a shorter isoprenoid (phytyl) chain which in which three of the four double bonds are reduced. In animals, both vitamins K1 and K2 act as cofactors for gamma-carboxylation of glutamate (Glu -> Gla) which is critical for coagulation factors. Note that an alternative pathway to menaquinone biosynthesis operates in Helicobacter pylori, Campylobacter jejuni, Streptomyces, and other species (see PMID:18801996). That pathway is not described here. |

menaquinone biosynthesis~Menaquinone may be synthesized by one of two independent pathways. The better known pathway, which includes MenA, MenB, etc., as found in Escherichia coli, passes through the intermediate SEPHCHC (see GenProp0058). An alternate pathway, found in both Helicobacter pylori and Streptomyces coelicolor, involves the intermediate futalosine (see GenProp0829). This property evaluates to YES is either menaquinone biosynthesis pathway is complete. |
