MbCo in Saccharide Solid Amorphous Systems: A Combined FTIR and SAXS Study

Abstract

Here we report a combined FTIR and SAXS study on MbCO embedded in dry amorphous matrices of trehalose and sucrose. FTIR measurements were performed at different protein/sugar ratios, focussing on the stretching band of the bound CO (COB) and on the Water Association Band (WAB), which are spectroscopic markers of the protein and the matrix, respectively
