Application
L-amino acid oxidase (LAAO) is used to convert L-amino acids to their corresponding α-keto acids. Product A2805 is from Crotalus durissus venom. L-amino acid oxidase, from Sigma, has been used in leucine aminopeptidase (LAP) activity assays .
Biochem/physiol Actions
L-amino acid oxidase is involved in various metabolic pathways such as alanine and aspartate metabolism, methionine metabolism, valine, leucine and isoleucine degradation, tyrosine metabolism, phenylalanine metabolism, tryptophan metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, and alkaloid biosynthesis . It is found in microorganisms and in animal tissue, especially in kidney and liver.

As opposed to single-cell yeast and mammalian cell lines, apoptosis has not been greatly investigated in filamentous fungi because antibodies to the relevant fungal apoptosis-related proteins are not available commercially and because multicellular organisms cannot be studied using flow cytometry.

Venoms of the redtail coral snake Micrurus mipartitus from Colombia and Costa Rica were analyzed by "venomics", a proteomic strategy to determine their composition. Proteins were separated by RP-HPLC, followed by SDS-PAGE, in-gel tryptic digestion, identification by MALDI or ESI
