Polivinil alkohol dehidrogenaza (citohrom) (EC 1.1.2.6, PVA dehidrogenaza, PVADH) je enzim sa sistematskim imenom polivinil alkohol:fericitohrom-c oksidoreduktaza.^{[1][2][3][4][5][6]} Ovaj enzim katalizuje sledeću hemijsku reakciju

polivinil alkohol + fericitohrom c ${\displaystyle \rightleftharpoons }$ oksidovani polivinil alkohol + ferocitohrom c + H⁺

Ovaj enzim učestvuje u degradaciji bakterijskih polivinilnih alkohola. Neke gram-negativne bakterije razgrađuju polivinilni alkohol putem njegovog unosa u periplazmatični prostor, gde se on oksiduje dejstvom polivinil alkoholne dehidrogenaza, enzima koji je spregnut sa respiratornim lancem putem citohroma c. Ovaj enzim sadrži pirolohinolin hinonski kofaktor.
