== Publication Abstract from PubMed == | |||
All living organisms face a variety of environmental stresses that cause the misfolding and aggregation of proteins. To eliminate damaged proteins, cells developed highly efficient stress response and protein quality control systems. We performed a biochemical and structural analysis of the bacterial CtsR/McsB stress response. The crystal structure of the CtsR repressor, in complex with DNA, pinpointed key residues important for high-affinity binding to the promoter regions of heat-shock genes. Moreover, biochemical characterization of McsB revealed that McsB specifically phosphorylates arginine residues in the DNA binding domain of CtsR, thereby impairing its function as a repressor of stress response genes. Identification of the CtsR/McsB arginine phospho-switch expands the repertoire of possible protein modifications involved in prokaryotic and eukaryotic transcriptional regulation. | |||
McsB is a protein arginine kinase that phosphorylates and inhibits the heat-shock regulator CtsR.,Fuhrmann J, Schmidt A, Spiess S, Lehner A, Turgay K, Mechtler K, Charpentier E, Clausen T Science. 2009 Jun 5;324(5932):1323-7. PMID:19498169<ref>PMID:19498169</ref> | |||
