“In Silico” Characterization of 3-Phytase A and 3-Phytase B from Aspergillus niger

Figure 10

General overview of the docking result between 3-phytase A and phytic acid (lowest energy = −6.3 kcal/mol). Active site (RHGXRXP-HD) consisting of residues R₅₈, , R₆₂, R₁₄₂, H₃₃₈, and versus phytic acid, visualized with the Autodock program. The red colored areas in the phytic acid correspond to regions with negative charge. Green dots refer to the H Bridges established between the ligand and the amino acids that form the active site in the protein.
