A PF09092 Lyase_N Lyase, N terminal Domain Members of this family are predominantly found in chondroitin ABC lyase I, and adopt a jelly-roll fold topology consisting of a two-layered bent beta-sheet sandwich with one short alpha-helix. The convex beta sheet is composed of five antiparallel strands, whilst the concave beta-sheet contains five antiparallel beta-strands with a loop between two consecutive strands folding back onto the concave surface. This domain is required for binding of the protein to long glycosaminoglycan chains [1]. PFAM PF09092
A PF09093 Lyase_catalyt Lyase, catalytic Domain Members of this family are predominantly found in chondroitin ABC lyase I, and adopt a helical structure, with fifteen alpha-helices which are at least two turns long and several short helical turns. The bulk of the domain is formed by ten alpha-helices forming five hairpin-like pairs and arranged into an incomplete toroid, the (alpha/alpha)5 fold. Additionally, two long and two short alpha-helices at the N terminus of the domain wrap around the toroid. At the C-terminal end of the toroid there is one additional short alpha-helix. This domain is required for degradation of polysaccharides containing 1,4-beta-D-hexosaminyl and 1,3-beta-D-glucoronosyl or 1,3-alpha-L-iduronosyl linkages to disaccharides containing 4-deoxy-beta-D-gluc-4-enuronosyl groups [1]. PFAM PF09093
A PF02278 Lyase_8 Polysaccharide lyase family 8, super-sandwich domain Family
A PF02884 Lyase_8_C Polysaccharide lyase family 8, C-terminal beta-sandwich domain Domain This family consists of a group of secreted bacterial lyase enzymes EC:4.2.2.1 capable of acting on hyaluronan and chondroitin in the extracellular matrix of host tissues, contributing to the invasive capacity of the pathogen.
