Abstract
The present invention consists of an analytical method for assay of L-glutamic acid in a sample by the use of an L-glutamic acid oxidase which is an L-amino acid oxidase catalyzing the oxidative deamination of the .alpha.-amino group of L-glutamic acid in the presence of water and oxygen to form .alpha.-ketoglutaric acid, ammonia and hydrogen peroxide, and having a very high substrate specificity for L-glutamic acid substantially without acting on L-glutamine and L-histidine, and also having a high stability, a reagent for analysis to practice the analytical method, a kit for analysis comprising the reagent, and a biosensor employing the enzyme.
