The LysM (lysin motif) domain is a small globular domain, approximately 40 amino acids long. It 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 [ PUBMED:1352512 ], 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 [ PUBMED:15120137 ]. 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 [ PUBMED:10369758 ].
