Membrane-associated genes with Pro codons near the initiation AUG codon in Vibrio cholerae, Haemophilus influenzae, Acinetobacter baumannii, and Pseudomonas aeruginosa. The gene sequences are retrieved and presented as in Figure 2. For Pseudomonas, genes with three consecutive Pro codons around 30th to 40th position are also shown. The strain for each species is: Vibrio cholerae O1 El Tor N16961, Haemophilus influenzae Rd KW20, Acinetobacter baumannii ATCC 17978, and Pseudomonas aeruginosa PAO1 and PA7.
