L-氨基酸氧化酶 来源于东部菱背响尾蛇毒液, ≥4 units/mg protein
Product Name: L-Amino Acid Oxidase from Crotalus adamanteus Venom
CAS号:9000-89-9
介绍: L-Amino Acid Oxidase is an oligomeric glycoprotein composed of unequal amounts of two different approximately 70 kDa subunits. Three electrophoretically different isozymes occur as different combinations of the two subunits. there are approximately two moles of FAD per mole of holo-enzyme. L-amino acid oxidase catalyzes the oxidative deamination of a number of L-amino acids. The enzyme is absolutely specific for L-isomers. The Aladdin product is prepared according to Wellner and Meister, JBC, 235, 2013, (1960) to the point just prior to crystallization.
用途: L-amino acid oxidase (LAAO) is used to convert L-amino acids to their corresponding α-keto acids. L-amino acid oxidase, from Sigma, has been used in leucine aminopeptidase (LAP) activity assays.
贮存: 储存温度 -20°C
生化和生理学机理: L-Amino acid oxidase is a flavoprotein with a molecular weight of 130 kDa. It consists of two different subunits of approximately 70,000 Da. Each molecule of holoenzyme has two FAD molecules. It is a glycoprotein containing about 2-5% carbohydrate, including sialic acid. Optimum pH is approximately 7.5.The enzyme may be reversibly inactivated by incubation in phosphate buffer, pH 7.5 at 38 °C. 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 occurs in many snake venoms apart from microorganisms and animal tissue, especially in kidney and liver.
