WebApr 14, 2024 · Tyrosine, Tryptophan, and phenylalanine are the three aromatic amino acids that collectively absorb the most energy, contributing the most to the absorbance peak at 280 nm. The UV-visible spectra of lysozyme alone and in presence of doxofylline at increasing concentrations in phosphate buffer (pH 7.4) are shown in Figure 1A. WebMentioning: 6 - The two tryptophan residues, Tip-248 and Trp330, in tryptophan indole-lyase (tryptophanase) from E. coii have been separately mutated to phenylalanine using site-directed mutagenesis. Both single tryptophan mutant enzymes have full catalytic activity, but exhibit different fluorescence and near-UV circular dichroism spectra. norman powell raptors
