WebL-Tryptophan decarboxylase ( EC 4.1.1.105) is an enzyme distinguished by the substrate L -tryptophan. [2] [3] This enzyme catalyzes the reaction of L -tryptophan to tryptamine and carbon dioxide. [2] [4] The enzymatic reaction namely takes place in the species Psilocybe cubensi s, where a decarboxylase, kinase, and methyltransferase work ... WebMoreover, compared the excitation spectrum of 1 with the UV–Vis absorption spectra of 1,3-DNB, the excitation wavelength was partially covered by the absorption spectra of 1,3-DNB (Fig. S12f). As a result, it can be inferred that the luminescence quenching is attributed to the adsorption of 1, 3-DNB by MOF 1 and accompanied by its framework decomposition, and …

The same … The fluorescence of a folded protein is a mixture of the fluorescence from individual aromatic residues. Most of the intrinsic fluorescence emissions of a folded protein are due to excitation of tryptophan residues, with some emissions due to tyrosine and phenylalanine; but disulfide bonds also have appreciable absorption in this wavelength range. Typically, tryptophan has a wavelength of maximum absorption of 280 nm and an emission peak that is solvatochromic, ranging from c…
