title: Class-3 porin protein of Neisseria meningitidis: cloning and structure of the gene.
abstract: The gene coding for the class-3 protein of Neisseria meningitidis was cloned and sequenced. The deduced amino acid (aa) sequence was highly homologous (50-78%) to those of other neisserial porin proteins. Alignment of the aa sequence of five neisserial porin proteins pinpointed several regions of identity or near identity. These are assumed to be membrane-spanning beta-strands. A comparison of the homologies between these neisserial porins showed that the class-3 protein is most closely related to the Neisseria gonorrhoeae P1A protein.
