Substrate binding to vanadate-dependent bromoperoxidase from Ascophyllum nodosum: A vanadium K-edge XAS approachElectronic supplementary information (ESI) available: Figure S1: Unit cells of compounds 3 and 7a, showing intermolecular hydrogen bonding. See http://www.rsc.org/suppdata/dt/b4/b405764c/
The EXAFS region of vanadium K-edge XAS spectra of native vanadate-dependent bromoperoxidase (isoenzyme I) from Ascophyllum nodosum in the presence of the substrate bromide can be fitted to three shells (at 1.62, 1.73-1.78 and 1.99-2.07 A) in the first coordination sphere of vanadium plus two more distant shells at 4.1A, possibly corresponding to bromide, and 4.7 A due to light scatterers stemming
