Fig. 3From: Evolutionary divergence of motifs in B-class MADS-box proteins of seed plantsProtein structural modelling of plant MADS domain (AT5G20240). A Overall structure (PDB: 1TQE) of human MEF2 (dimers) in complex with DNA and interacting protein (green color). B Superimposition of modelled AT5G20240 (yellow) with MEF2 (deep salmon). C Displays the spatial locations of motif 1 (cyan & red) and motif 9 (red), with DNA-binding residues shown in sticks. D Displays the identified dimerization residues in sticks. E Displays potential tetramerization residues in sticks. F Displays residues (sticks) involved in protein–protein interaction. Amino acid numbering is according to the M domain of AT5G20240Back to article page
