Principal Component Analysis (PCA) of the amino acid composition of proteins from known thermophilic and psychrophilic organisms, from the CAPP database and from the high- and medium-quality MAGs retrieved from the CAPP database. Vectors indicate the direction of the amino acid effect in the proteins' sequence composition specific to each organism and MAG. Eigenvalues are reported in Appendix C (Table C5).
