Clan: LysM (CL0187)


LysM-like domain Add an annotation

The LysM domain (Pfam:PF01476) is thought to be a general peptidoglycan-binding module. Although originally described in bacterial proteins, it has been also found in some eukaryotic sequences. It takes up a beta-alpha-alpha-beta conformation, with the beta strands forming an antiparallel beta sheet and the two alpha helices packing on one side of this sheet [1].

This clan contains 3 families and the total number of domains in the clan is 29949. The clan was built by M Fenech.

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the MSD group, to allow us to map Pfam domains onto UniProt three-dimensional structures. The table below shows the mapping between the Pfam families in this clan, the corresponding UniProt entries, and the region of the three-dimensional structures that are available for that sequence.
