Sequence frequency of amino acid residues of branch a6’ (colored) and other branches (black). Generated by WebLogo (http://weblogo.berkeley.edu/logo.cgi) (Crooks et al., 2004). The amino acid positions are numbered relative to alfalfa CHS2. Protein secondary structures of protein were predicted based on the three dimensional structure of alfalfa CHS2 (1BI5). Stars show the significant positive sites estimated by the Branch-sites models.
