hKOR-T4L was expressed in Spodoptera frugiperda (Sf9) cells. Ligand-binding and functional assays were performed as described in Methods. Sf9 cells were solubilized using 1% (w/v) n-dodecyl-β-D-maltopyranoside (DDM) and 0.2% (w/v) cholesteryl hemisuccinate (CHS), and purified by immobilized metal ion affinity chromatography (IMAC), followed by reverse IMAC after cleaving N-terminal FLAG-10xHis tags by His-tagged Tobacco Etch Virus (TEV) protease. The purified protein was mixed with monoolein and cholesterol in a ratio of 40%:54%:6% (w/w) to form lipidic cubic phase (LCP) from which the receptor was crystallized. Crystals were grown at 20 °C in 45 nl protein-laden LCP boluses overlaid by 800 nl of precipitant solutions as described in Methods. Crystals were harvested from the LCP matrix and flash frozen in liquid nitrogen. X-ray diffraction data were collected on the 23ID-B/D beamline (GM/CA CAT) at the Advanced Photon Source, Argonne, IL using a 10 μm minibeam at wavelength of 1.0330 Å. Data collection, processing, structure solution and refinement are described in Methods. Modeling of JDTic analogues and hKOR-selective morphine derivatives nor-BNI and GNTI was performed using ICM-Pro; SYBYL-X 1.3 and GOLD Suite 5.1 were used to model RB-64 complexes, as described in Methods.

BRIL-NOP was expressed in Spodoptera frugiperda (Sf9) insect cells. Ligand binding asays were performed as described in Methods online. Sf9 membranes were solubilized using 0.5% n-dodecyl-β-D-maltopyranoside (w/v) and 0.1% cholesteryl hemisuccinate (w/v), and purified by immobilized metal ion affinity chromatography (IMAC). Receptor crystallization was performed by the lipidic cubic phase (LCP) method. The protein-LCP mixture contained 40% (w/w) concentrated receptor solution, 54% (w/w) monoolein, and 6% (w/w) cholesterol. Crystals were grown in 40 nL protein-laden LCP bolus overlaid by 0.8 μL of precipitant solution (25–30% (v/v) PEG 400, 100–200 mM potassium sodium tartrate tetrahydrate, 100 mM BIS-TRIS propane [pH 6.4]) at 20 °C. Crystals were harvested directly from LCP matrix and flash frozen in liquid nitrogen. X-ray diffraction data were collected at 100 K on the 23ID-B/D beamline (GM/CA CAT) of the Advanced Photon Source at the Argonne National Laboratory using a 10 μm collimated minibeam. Diffraction data from 23 crystals were merged for the final dataset. Data collection, processing, structure solution and refinement are described in Methods online.

The full-length IgT gene of ASB was amplified with primers IgT NotI F and IgT XhoI R (Table S1 ) and inserted into pFastBac HT A transfer vector. The construct was integrated into the baculovirus genome with DH10BAC™ and the Bac-To-Bac system (Invitrogen). The bacmid DNA with IgT gene was purified for transfection into Spodoptera frugiperda (Sf9 III) cells (ATCC) for producing recombinant baculovirus (Bac-IgT). The Sf9 III cells were grown at 27°C in serum-free medium SF-900 III (Invitrogen). Procedures for the generation of recombinant baculovirus were carried out according to the manufacturer’s instructions (Invitrogen). Briefly, 1.2 X 106 Sf9 III cells were plated onto 6-well plates for 1 h. After attachment, 4 µg of recombinant bacmid DNA Bac-IgT and 10 µl Cellfectin II (Invitrogen) were diluted with culture medium and used for transfection of Sf9 III cells. Transfection was performed for 5 h at 27°C with the replacement of fresh SF-900 III medium after incubation. Transfected cells were kept at 27°C for 72 h. Following incubation, the supernatant containing recombinant viruses (Bac-IgT) was utilized for infection of fresh Sf9 III cells. For large scale viral production, Sf9 III cells were infected in suspension cultures of 2×106 cells/ml with the collection of supernatant four days post-infection.
