D-xylose 1-dehydrogenase (NADP+)

D-xylose 1-dehydrogenase (NADP+) is an enzyme that catalyzes the chemical reaction of D-xylose into D-xylono-1,4-lactone. This enzyme belongs to the family of oxidoreductase, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is D-xylose:NADP+ 1-oxidoreductase.

Function

D-xylose 1-dehydrogenase (NADP+) is involved in the pentose and glucuronate interconversions pathway. This enzyme plays a crucial role in the metabolism of D-xylose, a sugar that is commonly found in the human body.

Structure

Like other enzymes, D-xylose 1-dehydrogenase (NADP+) is a protein that is composed of amino acids. The exact structure of this enzyme can vary depending on the specific organism in which it is found.

Clinical Significance

Deficiencies or mutations in the D-xylose 1-dehydrogenase (NADP+) enzyme can lead to various health conditions. For instance, it has been linked to metabolic disorders such as Pentosuria, a rare condition characterized by the excessive excretion of D-xylose in the urine.
