FIG. 2.

Comparison of the protein sequences of F and R100-1 TraN. F TraN sequence is derived from nucleotides 12997 to 14802 of the F tra operon and corrected from a previously published sequence (12 [GenBank accession no. U01159]). R100-1 traN was sequenced as described in Materials and Methods. The sequence of R100-1 traN is contained within a larger fragment of R100-1 sequence (nucleotides 8469 to 10322; GenBank accession no. AF005044). The sequences were aligned with the GCG Pileup program and shaded with the Genedoc program (http://www.cris.com/∼ketchup/genedoc.shtml). Single-letter amino acid codes are used; conserved amino acids are shaded in black, with amino acid residues corresponding to either F or R100-1 TraN numbered on the right. Dashes are used to indicate gaps in the sequence generated during computer alignment.
