摘要
The synthesis of selectively C-14-labeled L-tryptophan and its derivative 5-hydroxy-L-tryptophan using chemical and multienzymatic methods is reported. The mixture containing [1-C-14[-DL-alanine, indole or 5-hydroxyindole has been converted to [1-C-14]-L-tryptophan or 5'-hydroxy-[1-C-14]-L-tryptophan, respectively, in a one-pot multienzymatic reaction using four enzymes: D-amino acid oxidase, catalase, glutamic-pyruvic transaminase and tryptophanase.
