Decaprenylphospho beta D ribofuranose 2 oxidase

Decaprenylphospho-beta-D-ribofuranose 2-oxidase (EC 1.1.98.3, decaprenylphosphoryl-beta-D-ribofuranose 2'-epimerase, Rv3790, DprE1) is an enzyme with systematic name trans,octacis-decaprenylphospho-beta-D-ribofuranose:FAD 2-oxidoreductase. This enzyme catalyses the following chemical reaction

trans,octacis-decaprenylphospho-beta-D-ribofuranose + FAD ⇌ trans,octacis-decaprenylphospho-beta-D-erythro-pentofuranosid-2-ulose + FADH₂

This enzyme from the bacterium Mycobacterium smegmatis participates in epimerization of trans,octacis-decaprenylphospho-beta-D-ribofuranose to trans,octacis-decaprenylphospho-beta-D-arabinoofuranose.
