| Abstract: | The nucleotide sequences of five finP alleles from various IncF plasmids (finP types I to V) as well as of three finP mutations were determined and compared. The finP gene specificity could be attributed to a variable, six-to-seven-nucleotide loop located between inverted repeats, and the sequence data were consistent with the product of finP being an RNA molecule rather than a protein. The finP mutations interrupted a proposed finP promoter or destabilized a predicted stem-and-loop structure in the finP RNA molecule. |
