PKLR one of three rate-limiting enzymes in glycolysis. It catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to ADP, yielding one molecule ATP and a pyruvate molecule, which is a central metabolic intermediate that can be used as a building block or oxidized further. There are several mammalian isozymes of pyruvate kinase encoded by different genes. The L type predominates in liver, and the M type in muscle and brain. Two alternatively spliced human isoforms have been described: the R- and L-types. Note: This description may include information from UniProtKB.
