Abstract
A method for selectively and easily quantifying the L-form and/or D-form amino acids to be measured using an aminoacyl tRNA synthetase (AARS) with high sensitivity, and an amino acid quantification kit. A method for quantifying amino acids (L-AA and/or D-AA) in a sample using an AARS, wherein the amino acids and the AARS are released from an aminoacyl AMP-AARS complex once formed, and they are used again for forming the aminoacyl AMP-AARS complex, so that reaction products such as pyrophosphoric acid to be measured can be ultimately produced up to a molar number larger than that of the amino acids contained in the sample, and an amino acid quantification kit for performing the method.
