| Research Abstract |
The futalosine pathway is operating in some bacteria for the biosynthesis of menaquinone. Futalosine is converted into dehypoxanthinyl futalosine (DHFL) by MqnB.In this study, three routes to the formation of DHFL were suggested. DHFL may have been directly formed by MqnB in Thermus thermophilus. In Streptomyces coelicolor, aminodeoxy FL (AFL) was converted to FL by deaminases, then to DHFL. In contrast, MqnB of Helicobacter pylori directly converted AFL into DHFL.
To identify compounds that specifically inhibit the futalosin pathway, we used B. halodurans that has FL pathway as a test strain. Finally, two candidate fungal culture broths were obtained.
