Is specific for donor substrates containing a stem tetrapeptide since it cannot use pentapeptide stems. Is essential for virulence in a mouse model of acute infection.<ref>PMID:20305661</ref> | ||

| + | The l,d-transpeptidases (Ldts) are promising antibiotic targets for treating tuberculosis. We report screening of cysteine-reactive inhibitors against LdtMt2 from Mycobacterium tuberculosis. Structural studies on LdtMt2 with potent inhibitor ebselen reveal opening of the benzisoselenazolone ring by a nucleophilic cysteine, forming a complex involving extensive hydrophobic interactions with a substrate-binding loop. | ||
