Conserved lipoprotein H.8 of pathogenic Neisseria consists entirely of pentapeptide repeats.
The pathogenic Neisseria, N. gonorrhoeae and N. meningitidis, possess an outer membrane protein (OMP), designated H.8, with a conserved monoclonal antibody (MAb)-binding epitope. We determined the DNA sequence of a gonococcal H.8 gene, and confirmed the relationship between the cloned gene and the H.8 OMP by constructing a gonococcal mutant lacking H.8. The predicted H.8 OMP is a lipoprotein 71 amino acids in length, composed of 13 repeats of a consensus sequence AAEAP with perfect 5-residue periodicity. The AAEAP units form a repeating epitope that comprises the entire predicted sequence of the protein.
