RESUMO
The protein IAs of serum-sensitive (FA635) and serum-resistant (FA638) transformants of Neisseria gonorrhoeae, which have identical pedigrees, have been shown to be different by the use of a monoclonal antibody and were also shown to be different by proteinase K cleavage and primary structural and surface peptide mapping. The difference in structure is within the surface-exposed region of the molecule. The only other difference observed between the two strains was a very slight difference in lipooligosaccharide silver staining in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. These data suggest that protein I alone or in combination with lipooligosaccharide may significantly contribute to serum resistance.
