Lytic transglycosylases catalyze the cleavage of the beta-1, 4-glycosidic, bond between N-acetylmuramic acid (MurNAc) and N-acetylglucosamine, (GlcNAc) in peptidoglycan with concomitant formation of a 1,6-anhydro bond, in the MurNAc residue. To understand the reaction mechanism of Escherichia, coli lytic transglycosylase Slt35, three crystal structures have been, determined of Slt35 in complex with two different peptidoglycan fragments, and with the lytic transglycosylase inhibitor bulgecin A. The complexes, define four sugar-binding subsites (-2, -1, +1, and +2) and two, peptide-binding sites in a large cleft close to Glu162. The Glu162 side, chain is between the -1 and +1 sugar-binding sites, in agreement with a, function as catalytic acid/base. The complexes suggest additional, contributions to catalysis from Ser216 and Asn339, residues which are, conserved among the MltB/Slt35 lytic transglycosylases.

[https://www.uniprot.org/uniprot/MLTB_ECOLI MLTB_ECOLI] Murein-degrading enzyme. Catalyzes the cleavage of the glycosidic bonds between N-acetylmuramic acid and N-acetylglucosamine residues in peptidoglycan. May play a role in recycling of muropeptides during cell elongation and/or cell division.
