Propanoic acid in the substrate entry channel. (A) Product binding in monomer A of the full length recombinant ALDHTt. The residues of the anchor loop (Cyan) are shown in stick and labeled. Potential hydrogen bonds between the propanoic acid (Green) and the protein residues are shown. (B) Product binding in monomer B, highlighting a different orientation of the carboxyl group. Glu261 orientation is shown only when the side chain was visible in the structure. The distance between the propanoic acid and the cysteine residue is shown in both structures.
