WebIntrinsic fluorescence of proteins in solution is commonly measured in order to detect changes in protein conformation, e.g., due to different solution conditions (pH, excipients, … WebThe intrinsic tryptophan fluorescence emission spectra of Sac7 and Sso7 (5 p, Af protein in 10 mM KH2PO4, pH 6.8) are obtained with excitation at 295 nm using 4 nm excitation and emission slit widths. Excitation at 295 nm prevents contributions from the two tyrosine and two phenylalanine residues.
WebFluorescence and phosphorescence measurements have been carried out on single-p tryptophan (Trp 43 or Trp 75)-containing mutants of Tet repressor (Tet R). Tet R containing Trp 43, the residue localized in the DNA recognition helix of the repressor, has been used to observe the binding of Tet R to two 20-bp DNA sequences of tet O1 and tet O2 operators. WebUniquely, UVR8 uses intrinsic tryptophan for UV-B perception with a homodimer structure containing 26 structural tryptophan residues. ... Here, using ultrafast fluorescence spectroscopy, ...
