PGK2 is a testis-specific form of phosphoglycerate kinase. Initially assumed to be a pseudogene, this protein is actually a functional phosphoglycerate kinase that catalyzes the reversible conversion of 1,3-bisphosphoglycerate to 3-phosphoglycerate, during the Embden-Meyerhof-Parnas pathway of glycolysis, in the later stages of spermatogenesis Source: Recombinant protein corresponding to aa1-417 from human PGK2, fused to His-tag at N-terminal expressed in E. coli. Molecular Weight: ~46.9kD (437aa) Specific Activity: >500units/mg, one unit will convert 1umole of 1,3-Bisphosphoglycerate to 3-PGA/minute at pH 8.0 at 37C.
