Alcohol dehydrogenase (cytochrome c) (EC 1.1.2.8, type I quinoprotein alcohol dehydrogenase, quinoprotein ethanol dehydrogenase) is an enzyme with systematic name alcohol:cytochrome c oxidoreductase.[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction

a primary alcohol + 2 ferricytochrome c an aldehyde + 2 ferrocytochrome c + 2 H+

A periplasmic PQQ-containing quinoprotein is present in Pseudomonas and Rhodopseudomonas.
