Figure 3

Tridimensional structure of TcPR-4b obtained by homology modeling with the barley Barwin protein (PDB code 1BW3_A.pdb) as template using SWISS-MODEL. A. Alignment of TcPR-4b with the barley Barwin protein. B. Ribbon representation of the TcPR-4b structure. The secondary structures are indicated by different colors: α-helices in red, β-strands in green and P-loops in blue. Dots indicate conserved cysteine residues forming disulfide linkages C49-C81, C70-C104 and C84-C143. C. Molecular surface of TcPR-4b with the T97 putative phosphorylation site indicated in yellow. D. Molecular surface position of conserved amino acids H31, H130, D110 e R27 which are highlighted in yellow. E. Molecular surface position of the regions 35-41 and 109-111 are indicated in pink.
