Beta-apo-4'-carotenal oxygenase (EC 1.2.1.82, beta-apo-4'-carotenal dehydrogenase, YLO-1, carD (gene)) is an enzyme with systematic name 4'-apo-beta,psi-carotenal:NAD oxidoreductase. This enzyme catalyses the following chemical reaction:

4'-apo-beta, psi-caroten-4'-al + NAD + H2O ${\displaystyle \rightleftharpoons }$ neurosporaxanthin + NADH + 2 H

Neurosporaxanthin is responsible for the orange color of Neurospora.
