Other name(s): decaprenylphosphoryl-β-D-ribofuranose 2'-epimerase; Rv3790; DprE1; decaprenylphospho-β-D-ribofuranose 2-oxidase
Systematic name: trans,octacis-decaprenylphospho-β-D-ribofuranose:FAD 2-oxidoreductase
Comments: The enzyme, isolated from the bacterium Mycobacterium smegmatis, is involved, along with EC 1.1.1.333, decaprenylphospho-D-erythro-pentofuranosid-2-ulose 2-reductase, in the epimerization of trans,octacis-decaprenylphospho-β-D-ribofuranose to trans,octacis-decaprenylphospho-β-D-arabinofuranose, the arabinosyl donor for the biosynthesis of mycobacterial cell wall arabinan polymers.
