IntEnz Enzyme Nomenclature
EC 1.1.1.179

Names

Accepted name:
D-xylose 1-dehydrogenase (NADP+, D-xylono-1,5-lactone-forming)
Other names:
D-xylose (nicotinamide adenine dinucleotide phosphate) dehydrogenase [ambiguous]
D-xylose-NADP dehydrogenase [ambiguous]
D-xylose:NADP+ oxidoreductase
Systematic name:
D-xylose:NADP+ 1-oxidoreductase (D-xylono-1,5-lactone-forming)

Reaction

Comments:

The enzyme, characterized from pig arterial vessels and eye lens, also acts, more slowly, on L-arabinose and D-ribose. Cf. EC 1.1.1.424, D-xylose 1-dehydrogenase (NADP+, D-xylono-1,4-lactone-forming).
