Abstract
A simple chromatographic procedure has been devised to separate gamma-glutamyl phosphate reductase and 1-pyrroline-5-carboxylate reductase, allowing the measurement of the former in crude Escherichia coli extracts. Analysis of a number of strains of E. coli has demonstrated that gene proA codes for gamma-glutamyl phosphate reductase and proB for gamma-glutamyl kinase. Introduction of a ColE1 hybrid plasmid containing the proA,B region into a strain with a chromosomal deletion of proA,B led to 3- and 17-fold increases in the specific activities of gamma-glutamyl kinase and gamma-glutamyl phosphate reductase, respectively.Entities:
