Tryptophan intrinsic fluorescence
WebFluorescence spectrum position suggested that at low temperature tryptophan accessibility increases upon protein-DMPC or protein-DPPC association. At temperatures above the protein transition (70 degrees C) tryptophan appears to interact significantly with the apolar phase of DMPC and DPPC, evidenced by spectral blue shifts. WebTryptophan and tyrosine are hydrophobic and hydrophilic aromatic amino acids respectively, which are also known for their intrinsic fluorescence nature in proteins. By observing the autofluorescence of both these hydrophobic and hydrophilic amino acids upon SDS treatment, information about SDS-protein interactions could be obtained.

WebTryptophan intrinsic fluorescence and circular dichroism spectroscopy corroborate these data. 15N-HSQC NMR indicates that ES-BAX is structured but some ES residues have suffered chemical shift perturbations, suggesting that the BH3 peptide interacts with some parts of the ES protein. ES and ES-BAX present similar stability to thermal denaturation.
