Summary
Lysozyme-like superfamily
Barley chitinase, bacterial chitosanase, and lysozymes from phage and animals all hydrolyse related polysaccharides. The proteins little amino-acid similarity, but have a structurally invariant core consisting of two helices and a three-stranded beta-sheet which form the substrate-binding and catalytic cleft [1].
This clan contains 21 families and the total number of domains in the clan is 83030. The clan was built by A Bateman.

Structures
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.
