Abstract:
1. A method for specifically detecting a primary amino acid in a sample, said method comprising: contacting said primary amino acid to be detected with a plurality of aminoacyl tRNA synthetases, wherein each member synthetase of said plurality differs from other member synthetases of said plurality according to the cognate primary amino acids thereof and wherein said plurality of tRNA synthetases comprises an aminoacyl tRNA synthetase cognate to said primary amino acid to be detected, and wherein said contacting is under reaction conditions capable of forming a product with said primary amino acid to be detected, wherein said product is selected from the group consisting of the aminoacyl-tRNA synthetase:amino acid AMP complex of said primary amino acid to be detected, inorganic pyrophosphate, the aminoacyl-tRNA corresponding to said primary amino acid to be detected, and AMP; thereby forming said product; and specifically detecting said product.
