Fig. 7. Heatmap representation of the variation of structural parameters of P219X (X= A, C, D, E, F, G, H, I, K, L, M, N, Q, R, S, T, V, W, Y) mutants with respect to the wild-type KR2 (WT-KR2).

Difference between WT-KR2 and mutant (a) dihedral angles, $\Delta {\mathrm{Torsion}}^{\mathit{WT},\mathit{MUT}}$ and (b) bond lengths, $\Delta {\mathrm{Bond}\mathrm{Length}}^{\mathit{WT},\mathit{MUT}}$. Counterclockwise (CCW) and clockwise (CW) orientation of the rPSBAT.
