title: Hybrid forms of phosphoglycerate mutase and 2,3-bisphosphoglycerate synthase-phosphatase.
abstract: Purified phosphoglycerate mutase from pig skeletal muscle and 2,3-bisphosphoglycerate synthase-phosphatase from pig erythrocytes were hybridized "in vitro". The hybrid showed a behaviour on electrophoresis and on ion-exchange chromatography similar to that of a naturally occurring enzyme with phosphoglycerate mutase, 2,3-bisphosphoglycerate synthase and 2,3-bisphosphoglycerate phosphatase activities present in pig skeletal and heart muscle. Both the hybrid and the muscle enzyme possess similar activities ratio. From these and previous data it is suggested that the six enzymatic forms with phosphoglycerate mutase, 2,3-bisphosphoglycerate synthase and 2,3-bisphosphoglycerate phosphatase activities detected in mammalian tissues (Carreras et al. 1981, Comp. Biochem. Physiol. 70B, 477-485) result from combination of three subunits (types M, B and E).
