產(chǎn)品描述：Bovine plasma amine oxidase has a molecular weight of 170 kDaand an optimum pH of 6.2 for spermine and 7.2 for spermidine. Amine oxidasesare divided into two classes: the pyridoxal and copper containing enzyme towhich plasma amine oxidase belongs, and the FAD-containing amino oxidases.Natural substrates include catecholamines, tryptamine derivatives and otherphysiologically active amines. Plasma amine oxidase is used in researchrequiring nitrogen group transfers. The molecule is composed of two identicalpolypeptide chains. There are two pyridoxal phosphates and two atoms of Cu+ permolecule. Bovine plasma amine oxidase is inhibited by copper chelating agents,many carboxyl reagents such as cuprizone, hydroxylamine and cyanide. Benzoicacid and benzyl alcohol are both non-competitive inhibitors (KI = 30 and 34mMrespectively). The assay for determination of amine oxidases employed atWorthington is essentially that of Tabor et al., JBC, 208, 645, (1954) with thereaction temperature reduced to 25℃
