Interactions across the monomer–monomer interface. A stereo ribbon drawing of one monomer–monomer interface. The residues involved in the interaction across the interface are drawn in sticks and colored differently according to monomers. Salt bridges include K175-E236, R63-E221, and D70-H207. Hydrogen bonds include R182-T22 and S65-N214. There is also water molecules involved in hydrogen bonds with protein residues. The residues R185 and F225 may form a π-cation interaction.
