UniProtKB - P9WI95 (PHOU2_MYCTU)
Protein
Phosphate-specific transport system accessory protein PhoU homolog 2
Gene
phoU2
Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Status
Functioni
Plays a role in the regulation of phosphate uptake. In this role, it may bind, possibly as a chaperone, to PhoR, PhoP or a PhoR-PhoP complex to promote dephosphorylation of phospho-PhoP, or inhibit formation of the PhoR-PhoP transitory complex (By similarity). Important for tolerance to antibiotics.By similarity1 Publication

Pharmaceutical usei
May be a drug target for designing new drugs that kill persister bacteria for more effective control of bacterial infections.
Disruption phenotypei
Defective in persistence phenotype shown by increased susceptibility to tuberculosis (TB) drugs rifampicin and pyrazinamide in both minimum inhibitory concentration (MIC) testing and drug exposure assays. The MICs of rifampicin and pyrazinamide decreased 4-fold and 2-fold, respectively. Reduced persistence in the mouse model of TB infection. Mutant was less able to survive and persist in the mouse lungs and spleens as shown by an about 10- to 30-fold decrease in colony forming unit (cfu) counts compared with the virulent strain.1 Publication
