Figure 6From: Comparable contributions of structural-functional constraints and expression level to the rate of protein sequence evolutionCorrelations between the evolutionary rate differences of domains within multidomain proteins and the same domain pairs from separate proteins. Each data point corresponds to a pair of SCOP superfamilies (S1, S2) that is observed at least once in the same multidomain protein in a genome. X-axis: mean of log10 of the ratios of evolution rates of all combination of domains (D i 1, D j 2) where D i 1 ∈ S1 and D j 2 ∈ S2. Y-axis: mean of log10 of the ratios of evolution rates of all combination of domains (D i 1, D j 2) where D i 1 ∈ S1, D j 2 ∈ S2 and (D i 1, D j 2) belong to the same multidomain protein. A – Human proteins. B – Randomized human protein sequences. C – Arabidopsis proteins. D – Randomized Arabidopsis protein sequences.Back to article page
