Figure 6From: Modeling coding-sequence evolution within the context of residue solvent accessibilityJoint analysis of the effects of both core size (small or large) and expression level (low or high) on the relationship between ω = dN/dS and RSA. Only the fitted lines are shown. Surprisingly, for low-expression genes, small-core proteins evolve faster than larger-core proteins. This relationship is reversed in a larger dataset obtained with less-stringent criteria (see text).Back to article page
