L-Amino Acid Oxidase from Crotalus adamanteus Venom is utilized in biochemical research for its ability to catalyze the oxidative deamination of L-amino acids, producing hydrogen peroxide, ammonia, and the corresponding keto acids. This enzymatic activity is particularly valuable in studies involving amino acid metabolism and oxidative stress. It is also employed in the development of biosensors for detecting amino acids in biological samples, leveraging the hydrogen peroxide generated as a measurable byproduct. Additionally, the enzyme's role in producing reactive oxygen species makes it a useful tool in investigating cellular oxidative damage and apoptosis mechanisms. Its application extends to pharmaceutical research, where it aids in the synthesis of specific keto acids and the exploration of enzyme inhibitors.
