We determined the nucleotide (nt) sequence of a mutation that confers proline overproduction and enhanced tolerance of osmotic stress on bacteria. The mutation, designated as proB74, is an allele of the Escherichia coli proB gene which results in a loss of allosteric regulation of the protein product, gamma-glutamyl kinase. Our sequencing indicated that the(More)
We constructed plasmids carrying the Escherichia coli proB gene that encodes γ-glutamyl kinase, under the control of the yeast GAL1 promoter. This construction was carried out with both the wild-type proB + gene and a mutant allele, proB74, that specifies an enzyme resistant to feedback inhibition by proline. Yeast pro1 mutants harboring these plasmids are(More)
