SAXS data from solutions of calcium/calmodulin-dependent protein kinase type II alpha (CaMKIIα) 6x hub domain with 5-HDC in 20 mM MES, 150 mM NaCl, 1 mM DTT, 100 µM 5-HDC, pH 6 were collected using a Xenocs BioXolver L with MetalJet (University of Copenhagen, Department of Drug Design and Pharmacology) equipped with a Pilatus3 R 300K detector at a sample-detector distance of 1.0 m and at a wavelength of λ = 0.13428 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 4.40 mg/ml was measured at 25°C. 10 successive 60 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
The data is a merge from data collected at two different configurations. In addition to the listed, data was collected on the same sample with sample-detector distance 1.4355 m (10 frames of 120 s). The data was collected for comparison with the CaMKIIa 6x hub domain without ligands present.
