Peanut encode a novel SCE1 subfamily. a Phylogenetic analysis of SCE1 sequences. The phylogenetic relationship of SCE1 protein sequences from Arabidopsis thaliana (At), Zea mays (Zm), Oryza sativa (Os), Glycine max (Gm) and Peanut was assessed by the neighbor-joining method using MEGA 5. The scale bar indicates the P distance. b Alignment sequences of Ad/AiSCE1a, Ad/AiSCE1b, AiSCE1c and Arabidopsis AtSCE1. The asterisk highlights the active-site Cys. Brown arrowheads located residues indicates an amino acid deletion in AiSCE1b and AdSCE1b. Gray and black boxes indicate similar and conserved amino acids, respectively. Dashes denote gaps. c Electrostatic surface charges surrounding the active-site Cys (green) are distinct between AiSCE1a and AiSCE1b. Surface electrostatics shown in two orientations were calculated using the Adaptive Poisson-Bolzmann Solver plugin in PyMOL. Blue indicates positive charges and red indicates negative charges
