Abstract

In Escherichia coli the levels of numerous enzymes associated with aerobic metabolism are decreased during anaerobic growth. In an arcA mutant the anaerobic levels of these enzymes are increased. The enzymes, which are encoded by different regulons, include members that belong to the tricarboxylic acid cycle, the glyoxylate shunt, the pathway for fatty acid degradation, several dehydrogenases of the flavoprotein class, and the cytochrome o oxidase complex. Transductional crosses placed the arcA gene near min O on the chromosomal map. Complementation tests showed that the arcA gene corresponded to the dye gene, which is also known as fexA, msp, seg, or sfrA because of various phenotypic properties [Bachmann, B. (1983) Microbiol. Rev. 47, 180-230]. A dye-deletion mutant was derepressed in the aerobic enzyme system. The term modulon is proposed to describe a set of regulons that are subject to a common transcriptional control.

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.
