Calcium/calmodulin-dependent protein kinase type II alpha (CaMKIIα) WT hub domain with PIPA (iii)

Data type: SASBDB experimental data Status: Published Curve type: Single concentration Last updated: 2024-09-18T12:54:56.214364+02:00

Several samples of CaMKIIa WT hub with PIPA were collected. This is sample (iii). The sample is not monodisperse but fitting attempted by a mixture of CaMKIIa WT hub dodecamers and multimers of self-associated (stacked) dodecamers. Only single and double dodecameric models are shown.

experiment_descriptionSAXS data from solutions of calcium/calmodulin-dependent protein kinase type II alpha (CaMKIIα) WT hub domain with PIPA in 20 mM MES, 150 mM NaCl, 1 mM DTT, 200 µM PIPA, 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 0.6 m and at a wavelength of λ = 0.13402 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 3.90 mg/ml was measured at 25°C. 40 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.
