The most efficient BCAA permease, BcaP, is subject to very strong transcriptional repression by CodY, a global regulator in B. Given the important role of BCAA in cell metabolism, it is not surprising that the synthesis of the permeases is strictly regulated and coordinated. ![]() National Institute of General Medical Sciences (GM042219) to ALS and the Pathway to Independence Award (GM099893) to SRB The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.Ĭompeting interests: The authors have declared that no competing interests exist.īraB is one of three permeases demonstrated to be involved in the uptake of branched-chain amino acids (BCAA) in Bacillus subtilis.

PLoS Genet 11(10):Įditor: Lotte Søgaard-Andersen, Max Planck Institute for Terrestrial Microbiology, GERMANY The increase in BraB expression only at intermediate activities of CodY may facilitate the uptake of BCAA when they are not in excess but prevent unneeded BraB synthesis when other BCAA transporters are active.Ĭitation: Belitsky BR, Brinsmade SR, Sonenshein AL (2015) Intermediate Levels of Bacillus subtilis CodY Activity Are Required for Derepression of the Branched-Chain Amino Acid Permease, BraB. We conclude that restricting increased expression of braB to conditions of moderate nutrient limitation is the raison d’être of the feed-forward regulatory loop formed by CodY and ScoC at the braB promoter. However, under conditions of reduced CodY activity, CodY-mediated repression was relieved to a greater extent than ScoC-mediated repression was increased, leading to elevated braB expression. ScoC-mediated repression of braB in codY null mutants cells was as efficient as direct, CodY-mediated repression in wild-type cells under conditions of high CodY activity. subtilis regulator, ScoC, whose own expression is repressed by CodY. Additionally, sequences upstream and downstream of the promoter were required for repression by a second pleiotropic B. A strong CodY-binding site located downstream of the transcription start point conferred negative regulation by direct interaction with CodY. This novel pattern of regulation was shown to be due to two opposing mechanisms, negative and positive, by which CodY affects braB expression. Nonetheless, expression from the braB promoter was significantly elevated in cells containing partially active mutant versions of CodY or in wild-type cells under growth conditions leading to intermediate levels of CodY activity. ![]() However, under conditions that maximize CodY activity, braB expression was similar in wild-type and codY null mutant cells.
