Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
D-xylose 1-dehydrogenase (NADP+) activity
Catalysis of the reaction: D-xylose + NADP(+) = D-xylono-1,5-lactone + H(+) + NADPH.
