== Function == | |||
[[http://www.uniprot.org/uniprot/LDT2_MYCTO LDT2_MYCTO]] Generates 3->3 cross-links in peptidoglycan, catalyzing the cleavage of the mDap(3)-D-Ala(4) bond of a tetrapeptide donor stem and the formation of a bond between the carbonyl of mDap(3) of the donor stem and the side chain of mDap(3) of the acceptor stem. 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> | |||

== Publication Abstract from PubMed == | |||
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. | |||
Targeting the Mycobacterium tuberculosis transpeptidase LdtMt2 with cysteine-reactive inhibitors including ebselen.,de Munnik M, Lohans CT, Lang PA, Langley GW, Malla TR, Tumber A, Schofield CJ, Brem J Chem Commun (Camb). 2019 Aug 5. doi: 10.1039/c9cc04145a.
