This entry represents the first LysM domain found in proteins from plants, including the NFP from Medicago truncatula and LYK from Arabidopsis thaliana. The LysM domain adopt a beta-alpha-alpha-beta fold, according to structure predictions and [1]. NFP/NFR5 class of receptors are crucial for initial lipochitooligosaccharide (LCO) perception and essential for LCO-mediated root nodule symbiosis [1]. LYK4 is a chitin-binding protein and contributes to chitin-triggered immunity [2]. LYK5 has been identified as a receptor with a very high affinity to chitooligosaccharides [2]. Receptors recognising Nod factors and chitin have a very similar structure but contain two diverging motifs in the LysM1 domain that are necessary for discriminating between immunity and symbiotic functions [3].

A	PF23472	LYK3/4/5 LysM2 domain (LysM2_CERK1_LYK3_4_5)	LYK3/4/5 LysM2 domain	This entry represents the second LysM domain found in proteins from plants, including LYK3 from Medicago truncatula, CERK1 and LYK4/5 from Arabidopsis thaliana. The LysM domain adopt a beta-alpha-alpha-beta fold, according to structure predictions. A ...	This entry represents the second LysM domain found in proteins from plants, including LYK3 from Medicago truncatula, CERK1 and LYK4/5 from Arabidopsis thaliana. The LysM domain adopt a beta-alpha-alpha-beta fold, according to structure predictions. Arabidopsis thaliana has retained the root developmental response to chitin-derived signals, utilising a widely conserved pathway involving CERK1 [1]. LYK4 is a chitin-binding protein and contributes to chitin-triggered immunity [2]. LYK5 has been identified as a receptor with a very high affinity to chitooligosaccharides [2]. Medicago LYK3 has an active intracellular kinase and Medicago NFP has a pseudokinase domain [3].	Domain
A	PF23473	LYK4/5 LysM3 domain (LysM3_LYK4_5)	LYK4/5 LysM3 domain	This entry represents the third LysM domain found in proteins from plants, including LYK4/5 from Arabidopsis thaliana. The LysM domain adopt a beta-alpha-alpha-beta fold, according to structure predictions. LYK4 is a chitin-binding protein and contri ...
