"description": "The quoted experimental MW is that determined from MALLS.",
"experiment_description": "Synchrotron SAXS data from solutions of hydroxypyruvate aldolase in 20 mM HEPES, pH 7.5 were collected using size exclusion chromatography SAXS (SEC-SAXS) on the EMBL P12 beam line at PETRA III (Hamburg, Germany) equipped with a Pilatus 6M detector at a sample-detector distance of 3 m and at a wavelength of λ = 0.124 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). The SEC parameters were as follows: An 80 μl sample at 8 mg/ml was injected at room temperature onto a GE Healthcare Superdex 200 Increase 10/300 column at a flow rate of 0.4 mL/min. 51 successive 1 second frames were collected through the lagging region of the SEC-elution peak that corresponded to the molecular weight (MW) of the hexamer (as assessed using multi-angle laser light scattering/refractive index measurements; MALLS/RI). The data were normalized to the intensity of the transmitted beam and radially averaged and the scattering of an appropriate solvent-blank was subtracted and the data scaled and averaged to produce the final SAXS profile displayed in this entry. CHROMIXS was used to process the SEC-SAXS data and assess the MW and Rg through the SEC peak (Rg and MW estimates and unsubtracted individual SEC-SAXS data frames are included in the full entry zip archive).",
