== Function ==
[https://www.uniprot.org/uniprot/LDT2_MYCTU LDT2_MYCTU] 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.<ref>PMID:24041897</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. PMID:31380528<ref>PMID:31380528</ref>
