Synchrotron SAXS data from solutions of AA9 LPMO in 50 mM MES, 150 mM NaCl, pH 6.5 were collected on the SWING beam line at SOLEIL (Saint-Aubin, France) using a Eiger 4M detector at a sample-detector distance of 2 m and at a wavelength of λ = 0.1033 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 4.3 mg/ml was injected at a 0.30 ml/min flow rate onto a Agilent AdvanceBio SEC 300Å, 4.6 x 150 mm column at 20°C. 600 successive 0.990 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.
ChAA9B was heterologously expressed in Pichia pastoris. The difference between the experimental molecular weight and the expected molecular weight is due to glycosylation.
