Lysin Motif is a small domain involved in binding peptidoglycan. LysM, a small globular domain with approximately 40 amino acids, is a widespread protein module involved in binding peptidoglycan in bacteria and chitin in eukaryotes. The domain was originally identified in enzymes that degrade bacterial cell walls, but proteins involved in many other biological functions also contain this domain. It has been reported that the LysM domain functions as a signal for specific plant-bacteria recognition in bacterial pathogenesis. Many of these enzymes are modular and are composed of catalytic units linked to one or several repeats of LysM domains. LysM domains are found in bacteria and eukaryotes.

Lysin motif.

LysM domain. The LysM (lysin motif) domain is about 40 residues long. It is found in a variety of enzymes involved in bacterial cell wall degradation. This domain may have a general peptidoglycan binding function. The structure of this domain is known.

spore coat assembly protein SafA. SafA (YrbB) (SafA) of Bacillus subtilis is a protein found at the interface of the spore cortex and spore coat, and is dependent on SpoVID for its localization. This model is based on the N-terminal LysM (lysin motif) domain (see pfamAM model pfam01476) of SafA and, from several other spore-forming species, the protein with the most similar N-terminal region. However, this set of proteins differs greatly in C-terminal of the LysM domaim; blocks of 12-residue and 13-residue repeats are found in the Bacillus cereus group, tandem LysM domains in Thermoanaerobacter tengcongensis MB4, etc. in which one of which is found in most examples of endospore-forming bacteria.
