mcsA | Activator of protein kinase McsB; Activates the phosphorylation activity of the protein- arginine kinase McsB. Is required for the delocalization of competence proteins from the cell poles. (185 aa) | ||||
mcsB | Protein tyrosine kinase; Catalyzes the specific phosphorylation of arginine residues in a large number of proteins. Is part of the bacterial stress response system, where it is involved in regulating the global heat shock repressor CtsR; phosphorylates arginine residues in the winged helix- turn-helix domain of CtsR, thereby preventing its binding to DNA and consequently inducing the expression of repressed genes. The transcriptional repressor HrcA, the chaperone GroEL, the unfoldase ClpC, together with several ribosomal subunits, represent other physiological targets of McsB under str [...] (363 aa) |
