Polyvinyl alcohol dehydrogenase (cytochrome)

Polyvinyl alcohol dehydrogenase (cytochrome) (EC 1.1.2.6, PVA dehydrogenase, PVADH) is an enzyme with systematic name polyvinyl alcohol:ferricytochrome-c oxidoreductase.^[1]^[2]^[3]^[4]^[5]^[6] This enzyme catalyses the following chemical reaction

polyvinyl alcohol + ferricytochrome c

\rightleftharpoons

oxidized polyvinyl alcohol + ferrocytochrome c + H⁺

This enzyme participates in bacterial polyvinyl alcohol degradation.
