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.
