Heterocyclic Bis-Cations as Starting Hits for Design of Inhibitors of the Bifunctional Enzyme Histidine-Containing Protein Kinase/Phosphatase from Bacillus s ubtilis
The main mechanism of carbon catabolite repression/activation in low-guanine and low- cytosine Gram-positive bacteria seems to involve phosphorylation of HPr (histidine- containing protein) at Ser-46 by the ATP-dependent HPr kinase, which in Bacillus subtilis, Lactobacillus casei, and Staphylococcus xylosus also exhibits phosphatase activity and is thus a bifunctional enzyme (HPrK/P). Since deficiency of HPrK/P in S. xylosus, L. casei, ...
