Summary:
Pantothenate kinase (PanK) catalyzes the phosphorylation of pantothenate (Pan) in the biosynthetic pathway of coenzyme A (CoA), a metabolic cofactor essential in multiple physiological processes including the citric acid cycle and fatty acid synthesis. Thus, PanK represents an important drug target for the design of antimicrobial agents, much needed for the treatment of multidrug-resistant bacterial strains that include E. coli, K. pneumoniae, P....
