EC 1.1.1.333     
Accepted name: decaprenylphospho-β-D-erythro-pentofuranosid-2-ulose 2-reductase
Reaction: trans,octacis-decaprenylphospho-β-D-arabinofuranose + NAD+ = trans,octacis-decaprenylphospho-β-D-erythro-pentofuranosid-2-ulose + NADH + H+

Other name(s): decaprenylphospho-β-D-ribofuranose 2′-epimerase; Rv3791; DprE2
Systematic name: trans,octacis-decaprenylphospho-β-D-arabinofuranose:NAD+ 2-oxidoreductase
Comments: The reaction is catalysed in the reverse direction. The enzyme, isolated from the bacterium Mycobacterium smegmatis, is involved, along with EC 1.1.98.3, decaprenylphospho-β-D-ribofuranose 2-oxidase, in the epimerization of trans,octacis-decaprenylphospho-β-D-ribofuranose to trans,octacis-decaprenylphospho-β-D-arabinoofuranose, the arabinosyl donor for the biosynthesis of mycobacterial cell wall arabinan polymers.
