Nucleotide sequence between the parA and traC genes of pBP136. The first nucleotide of the parA gene was redefined in this study and thus differs from the previously defined location (26). The numbers shown on the left of the sequence indicate nucleotide positions of pBP136. The insertion sites (inverted triangles) of Tn402/5053-like transposons in various IncP-1β plasmids are shown at homologous locations of the pBP136 sequence. Boxed sequences indicate three resolvase-binding regions (sites I to III) in the putative res site of the ParA resolvase of pBP136. Putative −10 and −35 sequences for parA are underlined. The sequence in bold and underlined represents the 20-bp IR. Sequence data for pB3, pB4, pB8, pB10, R751, pTP6, and pUO1 are compiled from the DDBJ/EMBL/GenBank databases: pB3, accession no. AJ639924; pB4, AJ431260; pB8; AJ863570; pB10, AJ564903; R751, U67194; pTP6, AM048832; and pUO1, AB063332.
