Abstract excerpt
Protein 1 (PI) is a major porin of Neisseria gonorrhoeae and Neisseria meningitidis and is encoded by a single locus, porB. Alleles of the porB locus of N. gonorrhoeae are assigned to two homology groups, PI(A) and PI(B), on the basis of immunological and structural similarity. In a like manner, alleles of the porB locus of the closely related bacterium, N. meningitidis, are allocated into class 2 and class 3...
