Abstract:Pyridomycin is a potent antimycobacterial natural product by specifically inhibiting InhA, a clinically validated antituberculosis drug discovery target. Pyridyl moieties of pyridomycin play an essential role in inhibiting InhA by occupying the reduced form of the nicotinamide adenine dinucleotide (NADH) cofactor binding site. Herein, we biochemically characterize PyrZ that is a multifunctional NadC homologue and catalyzes the successive formation, dephosphorylation, and ribose hydrolysis of nicotinic acid mon… Show more
