Synchrotron SAXS data from solutions of aldehyde dehydrogenase in 30 mM HEPES, 150 mM NaCl, 5% (v/v) glycerol, pH 7.5 were collected on the B21 camera at the Diamond Light Source (Oxfordshire, UK) using a Pilatus 2M detector at a sample-detector distance of 4.0 m and at a wavelength of λ = 0.1 nm ((Is) vs s, where s = 4πsinθ/λ and 2θ is the scattering angle). One solute concentration of 2.00 mg/ml was measured at 4°C. 18 successive 1 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged and the scattering of the solvent-blank was subtracted to obtain the SAXS profile displayed in this entry.
Aldehyde dehydrogenase (AldDH) is the N-terminal domain of the bifunctional alcohol/aldehyde dehydrogenase (AdhE; SASBDB entry SASDC72) spanning amino acids 1-445 of the full-length protein. SAXS data were measured from a protein construct that included a C-terminal 6 x histidine affinity chromatography tag. The buffer subtraction was performed using Scatter. Subsequent analysis was performed using PRIMUS (ATSAS 2.7.1).
