show Brenda entry

EC number

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

Comment

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.
