This domain is found at the N-terminal end of Pesticin from Yersinia pestis (Pst). Pst is a toxin that kills related bacteria of the same niche as Y.pestis. It is organised into three domains: an N-terminal translocation domain, the intermediate receptor binding domain (RB, this entry), and a C-terminal activity domain (Pfam:PF16754). This domain shows a beta-sheet of seven anti-parallel beta-strands together with three helices. It is essential for the intimate contact with the outer membrane protein receptor [1,2].	Domain
