Purity > 90% as determined by SDS-PAGE. MW: 45.4kDa. Full Length of Mature Protein: 27-259aa. N-terminal 10xHis-SUMO-tagged and C-terminal Myc-tagged. Campylobacter jejuni subsp. jejuni serotype O:23/36 (strain 81-176). Common antigen and a major cell adherence molecule. Most probably involved, with PEB1C, in a binding-protein-dependent transport system for an amino acid. May be involved in binding to intestinal cells
