Chemical modification of yeast 3-phosphoglycerate kinase.
Sulfhydryl reagents, as well as mild hydrogen peroxide oxidation, do not inhibit the activity of yeast phosphoglycerate kinase, indicating that the single thiol group and 3 methionine residues present in the enzyme are not essential for activity. Nitration of phosphoglycerate kinase by tetranitromethane inhibits the enzyme by reaction with a single tyrosine residue. Substrates provide partial p...
متن کاملA heat shock element in the phosphoglycerate kinase gene promoter of yeast.
The phosphoglycerate kinase (PGK) promoter is often employed in yeast expression vectors due to its very high efficiency. Its activity in unstressed cells has been shown to be due to an upstream activator site (UASPGK) at -402 to -479. Since levels of PGK mRNA can sometimes be elevated by heat shock of yeast cultures this investigation determined how specific deletions of PGK promoter sequences...
متن کاملHuman, yeast and hybrid 3-phosphoglycerate kinase gene expression in yeast.
When the gene for yeast 3-phosphoglycerate kinase (PGK) is present on a high copy number plasmid in Saccharomyces cerevisiae, 30-40 percent of yeast protein is produced as PGK. However, when the structural part of this gene is replaced by as many as twenty different heterologous genes, production of gene products is greatly reduced--usually by more than 20 fold. This decrease in protein product...

متن کاملCrystalline 3-phosphoglycerate kinase from skeletal muscle.
1. A procedure for preparing crystalline 3-phosphoglycerate kinase from rabbit or pig skeletal muscle is presented. 2. The preparation phosphorylates up to 975mumoles of 3-phosphoglycerate/min./mg. at 30 degrees and is not contaminated with myokinase. 3. The enzyme has an estimated molecular weight of 36500+/-1000, and contains three residues each of tyrosine and tryptophan. 4. The preparation ...
