In microorganisms, menaquinone is an obligatory component of the electron-transfer pathway. It is derived from chorismate by seven enzymes in Escherichia coli. However, a bioinformatic analysis of whole genome sequences has suggested that some microorganisms, including pathogenic species such as Helicobacter pylori and Campylobacter jejuni, do not have orthologs of the men genes, even though they synthesize menaquinone. We deduced the outline of this alternative pathway in a nonpathogenic strain of Streptomyces by bioinformatic screening, gene knockouts, shotgun cloning with isolated mutants, and in vitro studies with recombinant enzymes. As humans and commensal intestinal bacteria, including lactobacilli, lack this pathway, it represents an attractive target for the development of chemotherapeutics. << Less

In vitro reconstitution of the radical S-adenosylmethionine enzyme MqnC involved in the biosynthesis of futalosine-derived menaquinone.
Cooper L.E., Fedoseyenko D., Abdelwahed S.H., Kim S.H., Dairi T., Begley T.P.
The radical S-adenosylmethionine enzyme MqnC catalyzes conversion of dehypoxanthine futalosine (DHFL) to the unique spiro compound cyclic DHFL in the futalosine pathway for menaquinone biosynthesis. This study describes the in vitro reconstitution of [4Fe-4S] cluster-dependent MqnC activity and id ... >> More
The radical S-adenosylmethionine enzyme MqnC catalyzes conversion of dehypoxanthine futalosine (DHFL) to the unique spiro compound cyclic DHFL in the futalosine pathway for menaquinone biosynthesis. This study describes the in vitro reconstitution of [4Fe-4S] cluster-dependent MqnC activity and identifies the site of abstraction of a hydrogen atom from DHFL by the adenosyl radical. << Less
