data from solutions of
Conformational ensembles of domain–linker–domain (DLD) protein chimera consisting of Glycosyl hydrolase and Carbohydrate binding module 9
in
50 mM Na-phosphate, 2 mM TCEP, pH 6
were collected
on the
SWING beam line
at the SOLEIL storage ring
(Saint-Aubin, France)
using a Eiger 4M detector
at a sample-detector distance of 2 m and
at a wavelength of λ = 0.103 nm
(I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle).
In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 50.00 μl sample
at 9.5 mg/ml was injected at a 0.20 ml/min flow rate
onto a column
at 15°C.
630 successive
1 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.
All 50 conformers were refined using MoMa FReSa, which is available as an additional zipped file. |
