Trp and tyr residues
Webcontaining a significant amount of tryptophan (Trp) and tyrosine (Tyr) residues. The increased accuracy of this method takes into account the significant absorbance at 205 nm contributed by the aromatic side chains of Trp and Tyr. This method uses an A280/A205 ratio in its equation to correct for Trp and Tyr side-chain absorbance3. Recently ... WebMar 1, 2024 · There was an absorption peak at 210 and 280 nm in free α-La system, which represented the peptide skeleton structure and the aromatic amino acid residues (Trp and Tyr residues), respectively (Wang, Zhang, Zhang, Tao, & Tang, 2007). The absorption peak intensity of α-La at 280 nm changed after the addition of GA and GR, indicating that ...

WebApr 13, 2024 · The fluorescence quenching intensity of the Trp residues (Δλ = 60 nm) was substantially stronger than that of the Tyr residue (Δλ = 15 nm). The structure of the Try microregion was changed, with increased hydrophobicity and decreased polarity surrounding the residues, which is compatible with the fluorescence emission spectra … WebOct 26, 1999 · The Ar-density is the average count of aromatic residues {Phe, Trp, Tyr} within 5 Å of the reference amino acid. Sa levels strongly influence Ar-density values, showing a linear relationship paralleling the regular density distribution across the SC density values. This could be interpreted as a lack of specificity with a high affinity by ...
WebDec 5, 2014 · The Trp contribution to the emission of a protein containing both Trp and Tyr residues can be measured accurately without the need for synchronous spectra. This can be achieved by taking into account the fact that absorption by Tyr is practically negligible above 295 nm, while Trp absorption is still significant at this wavelength ( Fig. 6 A).
