In 4,155 orthologous sequences amino acid usage was analyzed by aligning the fiNOG-orthologous sequences of P. brachycephalum and Z. viviparus. The algebraic sign shows the direction of the imbalance of differential usage. Negative signs show a loss, positive signs show a gain of the corresponding amino acid in the Antarctic species. Most evident changes were emphasized and labelled with an asterisk.
