Synchrotron SAXS
data from solutions of
Truncation variant (amino acids 39-231) of Probable chromosome-partitioning protein ParB (vcParB1trunc I)
in
20 mM Tris pH 7.5, 100 mM NaCl, 5% glycerol, 1mM EDTA, 5 mM BME, 5 mM MgCl2
were collected
on the
BM29 beam line
at the ESRF storage ring
(Grenoble, France)
using a Pilatus 1M detector
at a sample-detector distance of 2.8 m and
at a wavelength of λ = 0.0999 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 100.00 μl sample
at 9.2 mg/ml was injected at a 0.07 ml/min flow rate
onto a GE Superdex 200 Increase 3.2/300 column
at 20°C.
1000 successive
2 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.
