Summary

Helicobacter pylori (H. pylori) infection causes peptic and duodenal diseases in humans. Among a 32-protein family of outer membrane proteins, a porin-like protein, HopE, has been a subject of note, mainly for its conservative nature among H. pylori, and for its potential as a vaccine candidate. To achieve stable surface expression of this host cell-toxic protein, hopE gene was introduced into pBAD expression system. After induction with arabinose, all 15 randomly-chosen E. coli LMG 194 colonies from 3 successive passages could express HopE protein, while only 1 from 5 E. coli colonies that contained lac operon-regulated plasmid encoding hopE gene could express HopE. Indirect immunofluorescence confirmed the expression of HopE on E. coli cell surface.
