Protein: Glucose-6-phosphate 1-dehydrogenase (G6PD) (EC 1.1.1.49) (P11413)
Organism: Homo sapiens (Human)
Function: Catalyzes the rate-limiting step of the oxidative pentose-phosphate pathway, which represents a route for the dissimilation of carbohydrates besides glycolysis. The main function of this enzyme is to provide reducing power (NADPH) and pentose phosphates for fatty acid and nucleic acid synthesis.
