title: cDNA encoding type B subunit of rat phosphoglycerate mutase: its isolation and nucleotide sequence.
abstract: A cDNA encoding the nonmuscle-specific (type B) subunit of phosphoglycerate mutase (PGAM-B) was isolated and characterized. A cDNA probe, synthesized by the polymerase chain reaction (PCR) from rat liver cell mRNA using mixed primers specific to the amino acid sequence of human PGAM-B, was used to screen a rat liver cell cDNA library. The identity of the cDNA was confirmed by amino acid sequence data for 24 peptides obtained by digesting the purified protein with three different endopeptidases. The coding region encoded a polypeptide composed of 253 amino acid (plus the initiator Met). RNA blot analysis showed a single mRNA species of 1.7 kilobases in rat liver cell. The deduced amino acid sequence of rat PGAM-B was identical to that of human PGAM-B except for only one substitution at position 251 near the carboxyl terminus (valine for the rat and alanine for the human).
