Morphine-6-dehydrogenase RFC25

The structural gene morphine-6-dehydrogenase (morA) was first isolated from Pseudomonas putida M10 as it is capable of growth with morphine as its sole carbon source¹. Morphine dehydrogenase (MDH) catalyses the oxidation of both morphine and codeine to produce morphinone and codeinone respectively. During this process NADP⁺ is reduced to NADPH which means that this enzyme is frequently used to detect morphine and codeine².
