Details of structure prediction. a Predicted models of Pi-ta protein variants and wPi-ta (Type I) using the Phyre2 server. The images are coloured by rainbow N to C terminus. b Confidence summary of predicted models, and the table has shown the dimension of predicted models of Pi-ta protein variants using three coordinates (X-axis, Y-axis, Z-axis), in Angstrom (Å)
