EC 18.104.22.168 - D-xylose 1-dehydrogenase (NADP+, D-xylono-1,5-lactone-forming)
IntEnz Enzyme Nomenclature
D-xylose-NADP dehydrogenase [ambiguous]
- D-xylose + NADP+ = D-xylono-1,5-lactone + NADPH + H+
The enzyme, characterized from pig arterial vessels and eye lens, also acts, more slowly, on L-arabinose and D-ribose. Cf. EC 22.214.171.1244, D-xylose 1-dehydrogenase (NADP+, D-xylono-1,4-lactone-forming).
