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. WebL-Tryptophan has the largest contribution to the absorption spectrum of a protein on a by-amino acid basis, thus it is commonly used as a standard to calibrate UV …
