Table 2 Estimation of the number of synonymous (dS) and nonsynonymous (dN) substitutions per site for ST8Sia genes by the branch-site model (PAML version 4.0).

From: Evolutionary history of the alpha2,8-sialyltransferase (ST8Sia) gene family: Tandem duplications in early deuterostomes explain most of the diversity found in the vertebrate ST8Sia genes

  1. For the 31 genes belonging to the different subfamilies, 271 codons have been taken into account; κ corresponds to estimated transition over transversion ratio and ω to dN/dS; (i) branches of interest, (b) background branches.
