Human-adapted Mycobacterium tuberculosis (Mtb) also infects animals and transmits zoonotically, threatening public health. The cell wall glycolipids lipoarabinomannan and lipomannan are essential virulence factors of Mtb. Phosphatidyl-myo-inositol mannosyltransferase PimA catalyzes a key step in their biosynthesis and...

Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), remains a major global health concern, particularly due to the emergence of drug-resistant strains. FAD-containing monooxygenase EthA activates the antitubercular prodrug ethionamide (ETH) in Mtb. However, the structural and functional mechanisms of Mtb Eth...
The found that the S15A, R145A or N175A mutants showed markedly reduced activity, whereas the K14A mutation completely abolished activity, and deletion of residues 27-101 (Δ27-101) led to a significant loss of function.
