THz spectroscopy is a very powerful tool in investigating the vibrational modes and conformational transitions of biomolecules. Here we have used THz spectroscopy to study the vibrational spectrum of bovine serum albumin, a protein whose 3D structure is yet unknown. Experimental data were fitted with theoretical spectra obtained by normal modes analysis of… (More)
The function of the epithelial Na+ channel from the apical membrane of many Na+ transporting epithelia is modulated by various chemical compounds from the extracellular space, such as heavy metals, protons or chloride ions. We have studied the effect of extracellular Cd2+ on the function of the epithelial Na+ channel (ENaC) in heterologously expressed… (More)
THz spectroscopy was used to investigate bovine serum albumin (BSA) flexibility in conditions ranging from lyophilised BSA to dilute 10% w/w BSA solution and highly concentrated 50% w/w BSA solutions. The simulated THz spectra of dry and hydrated BSA are in good agreement with the experiments.
