D-arabitol-phosphate dehydrogenase

D-arabitol-phosphate dehydrogenase (, APDH, D-arabitol 1-phosphate dehydrogenase, D-arabitol 5-phosphate dehydrogenase) is an enzyme with systematic name D-arabitol-phosphate:NAD+ oxidoreductase. This enzyme catalyses the following chemical reaction


 * D-arabitol 1-phosphate + NAD+ $$\rightleftharpoons$$ D-xylulose 5-phosphate + NADH + H+

This enzyme participates in arabitol catabolism. The enzyme also converts D-arabitol 5-phosphate to D-ribulose 5-phosphate at a lower rate.
