Figure 5.

Specific protein categories are significantly over-represented in their content of codon sites under positive or negative selection. (a) Functional categories of the MIPS FunCat proteins that show significant (P ≤ 0.01) enrichment of codon sites under positive (filled bars) or negative (open bars) selection. (b) Functional categories of the MIPS ProteinCat proteins that show significant (P ≤ 0.01) enrichment of codon sites under positive (filled bars) or negative (open bars) selection.
