Temperature-Induced Changes in Protein Structures Studied by Fourier Transform Infrared Spectroscopy and Global Analysis
Abstract
Fourier transform infrared (FTIR) spectroscopy has been used to study temperature-induced structural changes which occur in albumin, immunoglobulin G, fibrinogen, lysozyme, alpha-lactalbumin, and ribonuclease S when dissolved in 2H2O. In order to analyze the data, a new method was developed in which the data were analyzed globally with the aid of a spectral model. Seven or eight bands were sufficient to fit the full data set of spectra ranging from 1420 to 1760 cm-1 with a root mean square error of 1-2% of the maximum. Subsequently, the estimated band amplitude curves which showed a sigmoidal progression with increasing temperature were (globally) fitted with a two-state thermodynamic model. In this way, information on structural changes as well as on the thermal stability of the proteins was obtained. In all proteins investigated, enhanced 1H-2H exchange occurred at temperatures well below the unfolding of the secondary structure. This was interpreted as a change in tertiary structure leading to enhanced solvent accessibility. In all the proteins investigated, except for ribonuclease S, an intermolecular beta-sheet band indicative of aggregation appeared concomitant with the denaturation of the secondary structure. The results are compared with data from other techniques and discussed in terms of local unfolding and folding intermediates.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
