Synchrotron SAXS data from solutions of HIV-1 Reverse Transcriptase monomer (p66 subunit with W401A mutation) bound with Nevirapine in 20 mM Tris-HCl, 100 mM NaCl, 1 mM TCEP, pH 7 were collected on the BL1.3W beam line at the Synchrotron Light Research Institute (SLRI) storage ring (Nakhon Ratchasima, Thailand) using a Rayonix SX165 detector at a sample-detector distance of 1.7 m and at a wavelength of λ = 0.137 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 5.21 mg/ml was measured at 16°C. One 600 second frame was collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
