title: Isolation and identification of yeast messenger ribonucleic acids coding for enolase, glyceraldehyde-3-phosphate dehydrogenase, and phosphoglycerate kinase.
abstract: Yeast poly(adenylic acid)-containing messenger ribonucleic acid isolated from two strains of Saccharomyces cerevisiae was fractionated by preparative polyacrylamide gel electrophoresis in the presence of formamide. Three messenger ribonucleic acids, present at high intracellular concentration, were electrophoretically eluted from the polyacrylamide gels and translated in a wheat germ cell-free extract. The in vitro synthesized polypeptides were identified by tryptic peptide analysis. Messenger ribonucleic acids coding for enolase and glyceraldehyde-3-phosphate dehydrogenase were isolated from commercially grown baker's yeast (strain F1), and messenger ribonucleic acid coding for phosphoglycerate kinase was isolated from Saccharomyces cerevisiae (ATCC 24657). Significant differences in the spectrum of abundant messenger ribonucleic acids isolated from commercially grown baker's yeast (strain F1) and strain 24657 were observed. When both strains were grown under identical conditions, however, the spectrum of messenger ribonucleic acid isolated from the cells is indistinguishable.
