Molecular docking conformations and interactions between the enzyme and product for IaAS1_alpha (A,E), IaAS1_beta (B,F), IaAS2_alpha (C,G), and IaAS2_beta (D,H,I). The hydrogen bond donor and acceptor are colored as red and purple, respectively. Green and gray AA residues represent non-polar contact and any other contact, respectively. The first two AA residues were missing in the constructed structures; thus, the sequence number of AA residues is rearranged, i.e., ASP482 and TRP609 represent actual ASP484 and TRP611, respectively.
