FTIR Spectroscopy of Calcium-Binding Proteins 63 Fig. 2. (A) IR spectra of apo-calmodulin (c approx 11 mg/mL) in D 2O-buffer (100 mM Na-cacodylate, pH 7.0) after complete H/D exchange (solid line), together with the buffer spectrum (dashed line). For complete exchange of all amide protons with deuterons, the lyophylized protein was dissolved in D 2O-buffer and left overnight at room temperature. To eliminate the possibility of significant Ca 2+ -leaking from the infrared cell, the apo protein sample was placed in the CaF 2 cell immediately before the measurement, which was completed within less than 10 min. Infrared spectra were recorded on a Bruker IFS-66 FTIR spectrometer equipped with a DTGS detector. For each sample, 128 interferograms were co-addded and Fourier-transformed applying a Happ-Genzel apodization function to generate a spectrum with a nominal resolution of 4 cm –1 . (B) IR spectrum of the fully exchanged apo-form after subtraction of the buffer spectrum (solid line). The dashed line shows a correponding difference spectrum of only partly exchanged apo-CaM recorded 15 min after dissolution of the lyophilized protein in D 2O. 3.2.2. Residual Water Vapor It is almost impossible to remove all water vapor by purging of the spectrometer. In addition, the level always changes when the sample chamber is opened. It is therefore convenient to record spectra at low, but well-matched, levels of

(C) Infrared difference spectrum, obtained by subtracting the spectrum of the Ca 2+ -bound form from the spectrum of the Ca 2+ -free form. Note that the absorbance scale for the difference spectrum was expanded by a factor of 4. water vapor for the sample and the reference. A sample shuttle that allows the background to be signal averaged almost concurrently with the sample is very helpful. Residual water vapor can then simply be subtracted from the sample spectrum by using prerecorded water vapor spectra. This is mandatory for pro-
