Differences in amino acid composition.
P-values from paired Wilcoxon tests of differences in amino acid composition. Shown are the results from the analysis of (i) the mesophilic and psychrophilic groups of the complete dataset (column 2 and 4–9) and (ii) the intermediate and mesophilic group of the genus Vibrio (column 3).Complete sequences: The results for all the 66 membrane protein clusters. All: analysis of the mesophilic and psychrophilic groups of the complete dataset. Vibrio group: results for the intermediate and mesophilic group of the genus Vibrio. TMP: Results of 52 transmembrane proteins (TMP) are shown in columns 4–6. Tc: complete sequence of all TMP cluster. Tm: membrane helices of TMPs. To: sequence parts of TMPs outside the membrane. Signal peptides: Results from all 11 signal peptide clusters are shown in column 7–9. Sc: complete sequence of all signal peptides. Sm: signal sequence of signal peptides (anchor). So: sequence parts outside membrane. Differences with p-values< are shown in bold.
