Abstract

Bacterial motility and gene expression are controlled by a family of phosphorylated response regulators whose activities are modulated by an associated family of protein-histidine kinases. In chemotaxis there are two response regulators, CheY and CheB, that receive phosphoryl groups from the histidine kinase, CheA. Here we show that the response regulators catalyze their own phosphorylation in that both CheY and CheB can be phosphorylated in the complete absence of any auxiliary protein. Both CheY and CheB use the N-phosphoryl group in phosphoramidate (NH2PO3(2-)) as a phospho-donor. This enzymatic activity probably reflects the general ability of response regulators to accept phosphoryl groups from phosphohistidines in their associated kinases. It provides a general method for the study of activated response regulators in the absence of kinase proteins. CheY can also use intermediary metabolites such as acetyl phosphate and carbamoyl phosphate as phospho-donors. These reactions may provide a mechanism to modulate cell behavior in response to altered metabolic states.

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.
