Trp contents of the glucose-6-P transporters from Chlamydiaceae family organisms (center group) and from diverse other organisms. Each number in the column under the heading “p:P Trp Ratio” is the ratio of the Trp content of the transporter to the Trp content of the proteome. The genomic abbreviations, from top to bottom, are as follows: Lmon, Listeria monocytogenes 4b F2365; Spro, Serratia proteamaculans 568; Vvul, Vibrio vulnificus YJ016; Ppro, Photobacterium profundum SS9; PSYC, Psychromonas sp. CNPT3; Ecol, Escherichia coli K-12; Ahyd, Aeromonas hydrophila hydrophila ATCC 7966; Pamo, “Candidatus Protochlamydia amoebophila” UWE25; Cpne, Chlamydophila pneumoniae CWL029; Ctra, Chlamydia trachomatis D/UW-3/CX; Cmur, Chlamydia muridarum Nigg; Ccav, Chlamydophila caviae GPIC; Cfel, Chlamydophila felis Fe/C-56; Cdip, Corynebacterium diphtheriae NCTC 13129; Cbot, Clostridium botulinum A ATCC 3502; Saur, Staphylococcus aureus aureus MRSA252; and Bcer, Bacillus cereus ATCC 10987. The occurrences of Trp residues in an alignment are displayed as bold W's highlighted in yellow.
