title: Comparison of type IV-pilin genes of Pseudomonas aeruginosa of various habitats has uncovered a novel unusual sequence.
abstract: All known pilin sequences in Pseudomonas aeruginosa were amplified by a set of consensus primers located in the 5"-conserved region of pilA and the threonine-specific t-RNA following pilA. This also enabled the discovery of a novel pilin gene in a strain pair of clonal variants, which differs from known pilin genes in its increased GC-content. The mature protein has 173 amino acids making it the longest pilin known to date in P. aeruginosa. Different inserted sequences detected between the 3"-end of the pilin gene and the t-RNA in this strain and in strains with group I pilin genes seemed to be specific for each pilin group indicating a horizontal cotransfer of sequences.
