Quality assessment of modelled EhApc11 structure by QMEAN server. a Global quality estimation. b z-score value (− 2.46) of EhApc11 shown as a red star. c Local quality estimation. QMEAN scoring function depends on four individual components. Local geometry analysis is based on the potential of torsion angle over three consecutive amino acids. Long-range interactions are assessed at the residue level and at the second level based on the potential of Cβ atoms and all atoms, respectively. Solvation energy is calculated to know the accessibility of residues to water. The QMEAN z-score of − 4.0 or below is an indication of low model quality. The QMEAN z-score is shown on top, and individual z-scores are displayed below. The local quality plot is interpreted as the possibility of each residue of the model (on the x-axis) to be similar or deviable to the available native structures (on the y-axis). Residues with a score below 0.6 indicate deflection from expected values of native structures
