Purification of pig heart benzylamine oxidase.
International journal of molecular medicine, 1998A benzylamine oxidase (E.C. 1.4.3.6) has been purified from pig heart. Western blot analysis showed that the enzyme cross-reacts with a polyclonal antibody raised against homogeneous, crystalline pig plasma benzylamine oxidase (BAO). A subunit molecular mass of 97 kDa obtained by SDS electrophoresis is identical to the plasma enzyme.

Stereochemistry of Benzylamine Oxidation by Copper Amine Oxidases
Archives of Biochemistry and Biophysics, 1995Copper amine oxidases (EC 1.4.3.6) exhibit stereochemical heterogeneity in their reaction specificities. Enzymes isolated from different sources have previously been shown to catalyze the deamination of tyramine and dopamine with abstraction of the pro-R hydrogen at C-1, the pro-S hydrogen, and net nonstereo-specific protein abstraction.

Benzylamine oxidase in normal and atherosclerotic human aortae
Experimental and Molecular Pathology, 1983Assays of serum benzylamine oxidase (BzAO) have led some workers to postulate a relationship between elevated BzAO activity and diseases characterized by proliferating connective tissue. The present study was designed to determine whether BzAO activity of a cellular tissue is also affected.

Biochemical Pharmacology, 1982
The selectivity of benserazide and phenelzine toward inhibition of benzylamine oxidase (BzAO) and monoamine oxidases (MAO-A and MAO-B) was studied in homogenates of rat skull and lung. In addition, the kinetic interaction and reversibility of BzAO inhibition were assessed.

Stereospecific deamination of benzylamine catalyzed by different amine oxidases
International Journal of Biochemistry, 19881. Stereospecific deuterated benzylamine enantiomers, R(alpha-2H1)-and S(alpha-2H1)-benzylamine, were synthesized by a combined chemical and enzymatic method. 2. The retention or cleavage of the deuterium atom during deamination of benzylamine catalyzed by amine oxidases from different sources was assessed by a GC-MS procedure and confirmed by HPLC ...

Active-Site Titration of Pig-Plasma Benzylamine Oxidase
European Journal of Biochemistry, 19781. Titration of benzylamine oxidase with benzylamine under anaerobic conditions shows that full reduction of the enzymic 470-nm chromophore is obtained on the addition of one mole of substrate per mole of enzyme. Concomitantly, one mole of benzaldehyde per mole of enzyme is produced. 2.

Plasma Benzylamine Oxidase Activity in Cerebrovascular Disease
European Neurology, 2008The plasma benzylamine oxidase level (BzAO) was determined in 60 patients with different types of acute cerebrovascular disease, such as cerebral bleeding, subarachnoid bleeding and cerebral infarction. Patients with cerebral infarction included both apoplectic and multiple types.

Lysyloxidase and benzylamine oxidase in pig aorta.
The Italian journal of biochemistry, 1981Three enzymes were isolated from pig aorta: a benzylamine oxidase differing from the plasma type, and two different types of lysyloxidase. Some properties of the two types of lysyloxidase are described. The three enzymes were inhibited by cupric copper chelating agents and by carbonyl reagents.

Journal of Urology, 1984
The activity of monoamine oxidase type A (MAO-A) of rat uteri is known to be modulated by sex steroids but no information is available with regard to benzylamine oxidase (BzAO). Thus, uterine MAO-A and BzAO activities were assayed in ovariectomized (3 weeks) and ovariectomized plus estrogen treated rats (17 beta-estradiol, 10 micrograms/kg/day, i.p ...

Spermine oxidase and benzylamine oxidase. Distribution, development and substrate specificity
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1962Abstract A survey has been made of the distribution of the two types of amine oxidase that occur in mammalian blood plasma. Spermine oxidase has been found in all ruminants (Ruminantia and Tylopoda) examined, and also in the hippopotamus and two members of the order Hyracoidea.
