Significant Amino Acid Substitutions within Cotton GhACT Proteins.

The model was constructed using the spdbv37sp5 protein structure program (SwissModel first approach mode) from the Web site http://swissmodel.expasy.org/ of the Swiss Institute of Bioinformatics. Front (A), right side (B), back (C), and left side (D) views, respectively, of the space-filling model for cotton GhACT1. The GhACT1 structure was built based on the known actin three-dimensional structure. Substitutions involving charged or strongly polar amino acid interchanges among the 15 cotton actin isoforms (GhACT1 to GhACT15) are shown in the labeled amino acid residues.
