Fig. 5From: Enhancing thermal tolerance of Aspergillus niger PhyA phytase directed by structural comparison and computational simulationIllustration of mutated and catalytic residues in AnP-M2. Mutated residues in AnP-M2 are shown in spheres, substrate binding motif (orange) and catalytic motif (purple) are shown in cartoon (a). Distances between R248 in segment-3 of AnP-M2 and Y63 of the catalytic motif were shown in yellow dash (b)Back to article page
