Nucleotide sequence of the pilin gene of Bacteroides nodosus 340 (serogroup D) and implications for the relatedness of serogroups.
The gene encoding pilin of Bacteroides nodosus 340 has been isolated and the nucleotide sequence determined. The gene is present as a single copy within the B. nodosus genome and a protein of Mr 16683 can be predicted from the proposed coding region. A comparison of the predicted amino acid sequence with pilin from other strains of B. nodosus indicated that the protein of strain 340 (serogroup D) has a high degree of similarity with pilin of strain 265 (serogroup H). The degree of similarity between pilins from these strains and from other B. nodosus serogroups is no greater than that between B. nodosus pilins and the homologous proteins of several different bacterial species. These findings suggest that serogroups D and H may form a subset of B. nodosus serogroups.
