FIG. 2.

Sequence homology comparisons and hydropathy profiles of Snr-1. (A) Comparison of the predicted amino acid sequence of the Snr-1 protein of P. aeruginosa PAO1 (Pa) with the predicted amino acid sequence of cytochrome c of D. tiedjei DCB-1 (Dt). The signal peptide of D. tiedjei is labeled and in boldface type. The two c-type heme motifs are labeled and in boldface type. (B) Hydropathy profile of Snr-1, generated using the Mac Vector (6.1.1) computer program. Any measurement greater than 0.00 represents a hydrophilic amino acid. (C) Profile of Snr-1 transmembrane segments. Any measurement above 0.00 is considered a transmembrane segment.
