| Target description: | L-amino-acid oxidase (UniProt: Q96RQ9; also known as EC:1.4.3.2, LAAO, LAO, Interleukin-4-induced protein 1, IL4-induced protein 1, Protein Fig-1, hFIG1) is encode by the IL4I1 (also known as FIG1, UNQ636/PRO1265) gene (Gene ID: 259307) in human. LAAO is a flavoenzyme containing, non-covalently bound flavin adenine dinucleotide enzyme. It is widely distributed and catalyzes the stereospecific oxidative deamination of L-amino acids to produce alpha-keto acids and it also produces ammonia and hydrogen peroxide via an imino acid intermediate. The initial step in its action involves removal of two hydrogen atoms by the flavin coenzyme, with formation of an unstable -amino acid intermediate, which undergoes decomposition by addition of water and forms the ammonium ion and the corresponding -keto acid. LAAO has been shown to selectively bind to cell membranes of specific phospholipid composition and deliver the hydrogen peroxide to localized regions on the cell surface thereby inducing local oxidative stress. Common substrates for LAAO include L-isomers of leucine, isoleucine, nor-leucine, alpha-amino butyric acid, phenylalanine, tyrosine, tryptophan norvaline, methionine, histidine, and citrulline. LAAO is believed to contain three hydrophobic substrate binding sites, designated a, b, and c. Subsite a accommodates one methylene carbon, subsite b two, and subsite c accommodates three carbons. It also contains an amino binding subsite, which is designated as the d site. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. |
