additional information
identification of the the active tunnel of meso-2,3-BDH. The two short alpha-helices positioned away from the alpha4-helix possibly expose the hydrophobic ligand-binding cavity, gating the exit of product and cofactor from the activity pocket. AC binds in the active pocket including Ser139, Gln140, Ala141, Leu149, Tyr152, Gly183, Ile184, and Trp190. Residues Phe212 and Asn146 function as the key product-release sites. Three catalytic residues are Ser139, Tyr152, and Lys156. Docking study using the structure of meso-2,3-BDH (PDB ID 1GEG), molecular dynamics simulation
