Piruvat kinaza (EC 2.7.1.40) je enzim koji učestvuje u glikolizi. Ona katalizuje transfer fosfatne grupe sa fosfoenolpiruvata (PEP) na ADP, formirajući molekul piruvata i ATP-a.^[1]

Reakcija

Za rad piruvat kinaze je neophodan jon magnezijuma. Enzim se grupiše kao transferaza u međunarodnoj klasifikaciji enzima.

Piruvat kinaza posreduje finalni korak u glikolitičkom putu, kojim se formira piruvat, krajnji proizvod aerobne glikolize. U anaerobnoj glikolizi, laktat dehidrogenaza koristi NADH proizveden gliceraldehid fosfat dehidrogenazom da redukuje piruvat do laktata. Kod ljudi, postoje dva izozima piruvat kinaze: tip M (mišići, SwissProt P14618) i tip L,R (jetra i eritrociti, SwissProt P30613). Ovi izozimi se razlikuju po primarnoj strukturi i regulaciji.
