The crystal structure was determined in complex with darunavir with 1.8-Å resolutions. The crystal formed with one PR dimer in the asymmetric unit with two inhibitor molecules bound in alternative orientations.

Surface residues <scene name='Sandbox_Reserved_712/R45/1'>R45</scene> and <scene name='Sandbox_Reserved_712/R55/1'>R55</scene> had disordered side chains, but the other amino acid residue changes could be modeled into well-defined electron density maps.

PR<sub>DRV5</sub> contains darunavir mutations V82T and I84V (see Fig.2, Part B, indicated in bold print) that are directly involved in substrate-darunavir-interactions (change of S2/S2' subsites).
