The Gene-Enzyme Relationships of Proline Biosynthesis in Escherichia coli

Open access
HAYZER, D. J., LEISINGER, Th.·1980·Microbiology

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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
