Alcohol dehydrogenase (azurin)

Alcohol dehydrogenase (azurin) (, type II quinoprotein alcohol dehydrogenase, quinohaemoprotein ethanol dehydrogenase, QHEDH, ADHIIB) is an enzyme with systematic name alcohol:azurin oxidoreductase. This enzyme catalyses the following chemical reaction


 * primary alcohol + azurin $$\rightleftharpoons$$ aldehyde + reduced azurin

This enzyme is a periplasmic PQQ-containing quinohemoprotein.
