Wat (wie) is pyruvate kinase - definitie
CLASS OF ENZYMES
Pyruvate Kinase; EC 2.7.1.40; ATP:pyruvate 2-O-phosphotransferase
Pyruvate dehydrogenase kinase
Pyruvate dehydrogenase kinase (also pyruvate dehydrogenase complex kinase, PDC kinase, or PDK; ) is a kinase enzyme which acts to inactivate the enzyme pyruvate dehydrogenase by phosphorylating it using ATP.
MAP kinase kinase kinase
Mitogen Activated Protein (MAP) kinase kinase kinase, MAPKKK (or MAP3K) is a serine/threonine-specific protein kinase which acts upon MAP kinase kinase. Subsequently, MAP kinase kinase activates MAP kinase.
Pyruvate dehydrogenase deficiency
CARBOHYDRATE METABOLIC DISORDER CHARACTERIZED BY THE BUILDUP OF LACTIC ACID IN THE BODY AND A VARIETY OF NEUROLOGICAL PROBLEMS AND CAUSED BY A DEFICIENCY OF ONE OF THE THREE ENZYMES IN THE PYRUVATE DEHYDROGENASE COMPLEX
Pyruvate dehydrogenase complex deficiency disease; Deficiency of pyruvate dehydrogenase
Pyruvate dehydrogenase deficiency (also known as pyruvate dehydrogenase complex deficiency or PDCD) is a rare neurodegenerative disorders associated with abnormal mitochondrial metabolism. PDCD is a genetic disease resulting from mutations in one of the components of the pyruvate dehydrogenase complex (PDC).

Pyruvate kinase
Pyruvate kinase is the enzyme involved in the last step of glycolysis. It catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to adenosine diphosphate (ADP), yielding one molecule of pyruvate and one molecule of ATP. Pyruvate kinase was inappropriately named (inconsistently with a conventional kinase) before it was recognized that it did not directly catalyze phosphorylation of pyruvate, which does not occur under physiological conditions. Pyruvate kinase is present in four distinct, tissue-specific isozymes in animals, each consisting of particular kinetic properties necessary to accommodate the variations in metabolic requirements of diverse tissues.
