Synchrotron SAXS
data from solutions of
Apoptosis-stimulating protein 2 of p53 (ASPP2(905-1128)) bound to the serine/threonine-protein phosphatase PP1-alpha catalytic subunit, compact
in
25 mM Tris, 150 mM NaCl, 1 mM DTT, pH 8
were collected
on the
12.3.1 (SIBYLS) beam line
at the Advanced Light Source (ALS) storage ring
(Berkeley, CA, USA)
using a Pilatus3 X 2M detector
at a sample-detector distance of 2.1 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 sample
was injected at a 0.50 ml/min flow rate
onto a Shodex KW-800 series column
at 20°C.
800 successive
3 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.
Sample injection volume = UNKNOWN
