Extended Data Fig. 9: Comparison of conformational trajectories in MPV-loaded bCNT3 and apo nwCNT.
From: Antiviral drug recognition and elevator-type transport motions of CNT3
a, Structural superposition of bCNT3 (top left) and nwCNT (bottom left) conformers. Alignment based on the trimerization interface, TM3 and TM6. Relative positions of HP1 (middle) and HP2 (right), with lines denoting a marker residue for each conformational state. b, Transport domain movement quantified by its tilt angle relative to a representative IFS structure (X-axis) and distance displacement of nucleoside binding site center of mass (Y-axis). For bCNT3, coordinates corresponding to the highest resolution instance of each conformer used for the analysis (OFS-INT1-INT1 highest res; INT1-INT1-INT1 ‘condition 1’ ensemble analysis; INT2-INT2-INT2 ‘condition 2’ ensemble analysis; INT1-INT1-INT3 ‘condition 1’ ensemble analysis; all relative to the GS4 consensus IFS structure). c, Structural superposition of the transport domain for OFS, INT1, INT3, INT3 and IFS (NHC) structures. d, [3H]-ribavirin uptake (1.0 μM) in 10 minutes into oocytes expressing WT or mutant bCNT3 (n = 3; mean ± s.e.m. and individual replicates shown).
