Fig. 4. Molecular structure analysis of the recombinant phytase. (A) Molecular structure analysis of the recombinant phytase YiAPPA. (B) Molecular structure analysis of the recombinant phytase K189R/K216R. The blue parts in the figure represent the amino acid residues constituting the active site of the phytase. The red parts indicate the mutated amino acid residues (Lys^-189 mutated to Arg-189; Lys-216 mutated to Arg-216) and the amino acid residues forming new hydrogen bonds with them (Ala-184 forms a new hydrogen bond with Arg-189; Ser-218 forms a new hydrogen bond with Arg-216). Hydrogen bonds are outlined in the magenta dashed box.
