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].

This entry represents the second LysM domain found in proteins from plants, including the NFP from Medicago truncatula. 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]. The NFP LysM2 domain, and L154 in particular, are crucial for the entry step of rhizobia, suggesting that NFP is involved in specific NF recognition for infection [2].	Domain
A	PF23462	NFP LysM3 domain (LysM3_NFP)	NFP LysM3 domain	This entry represents the third LysM domain found in proteins from plants, including the NFP from Medicago truncatula. The LysM domain adopt a beta-alpha-alpha-beta fold, according to structure predictions and [1]. NFP/NFR5 class of receptors are cru ...	This entry represents the third LysM domain found in proteins from plants, including the NFP from Medicago truncatula. 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]. LysM3 also plays a role in infection, although a less important role than that of LysM2 [2].	Domain
