Webaromatic amino acids, mainly tryptophan, considering that phenylalanine has a very low quantum yield, and emission by tyrosine in native proteins is often quenched. Fluores … WebWhile the fluorescence quantum yield changes upon glucose binding, the enzyme's absorption spectra, emission spectra and fluorescence lifetimes change very little. These results are consistent with the existence of a dark complex for excited state Trp. Addition of glycerol, L-glucose, sucrose, or trehalose increases the binding affinity of glucose to the …
