Pyruvate kinase (PK) deficiency due to mutations of the PKLR gene is a common cause of hereditary nonspherocytic hemolytic anemia. Thus far, 55 different mutations have been described in patients with PK-deficient hemolytic anemia. Polymorphisms within the PKLR gene and i n the tightly linked glucocerebrosidase (GBA) gene suggest that PK deficiency may represent a balanced polymorphism.

By focusing in sucrose, gradient L-type pyruvate kinase from human liver could be separated into 2 major forms (pI 6.28 +/- 0.03 and 5.85 +/- 0.09) and a minor more acid form (pI = 5). These different forms could also be detected by focusing in acrylamide-ampholine slab gel. The major forms were int
Anti human M2 type and anti human L type pyruvate kinase sera allowed us to distinguish two groups of pyruvate kinase in man. Erythrocyte and liver (L type) enzymes on the one hand were inhibited by anti L and not all by anti M2 serum; pyruvate kinase from all the other tissues on the other hand wer
Hepatic pyruvate kinase phosphatase activity has been assayed in native conditions, in Sephadex G-25 filtered extracts of rat hepatocytes, by measuring the reactivation rate of glucagon-inactivated pyruvate kinase-L. The ionic requirements for this reaction, as well as the possible regulatory role o
