Manganese K-edge X-ray absorption spectroscopy of a crystal of phosphoenolpyruvate carboxykinase from Escherichia coli. (a) Normalized background-subtracted spectrum corresponding to the average of 12 individual scans. The inset shows the 1s → 3d feature expanded to show the detail. (b) Comparison of the Fourier transform of the k3-weighted EXAFS obtained from CLS 08B1-1 and SSRL 7-3 calculated using a k-range of 1–11.5 Å−1 and phase-correction for Mn—N backscattering. |
