titleOfInvention | Method of Analyzing L-Tryptophan in Biological Samples, and Kit Used Therein |
abstract | Disclosed is a method for quantifying L-tryptophan involving a step for mixing a specimen, L-tryptophan oxidase, and water, a step for allowing the obtained reaction solution to stand a predetermined period of time in the presence of oxygen, and a step for measuring the reaction product resulting from action of enzymes present in the reaction solution after allowing to stand. The L-tryptophan oxidase has a given amino acid sequence and has oxidase activity that generates hydrogen peroxide and ammonia by acting on the L-tryptophan in the presence of oxygen and water. The oxidase activity of the L-tryptophan oxidase on the L-phenylalanine is in the range of 0-3% of the oxidase activity thereof on the L-tryptophan, and the L-tryptophan oxidase does not have oxidase activity on protein-constituting amino acids other than L-tryptophan and L-phenylalanine. Also disclosed are a kit used to quantify the L-tryptophan containing L-tryptophan oxidase, and an enzyme sensor using the L-tryptophan oxidase. This method, kit and enzyme sensor use an L-tryptophan-specific enzyme, so are capable of quantifying L-tryptophan even in the presence of other amino acids. |
