The Kinetics of Reoxidation of Reduced Benzylamine Oxidase
European Journal of Biochemistry, 1977The mechanism of reoxidation of reduced benzylamine oxidase has been investigated at different pH between 6 and 10 by steady‐state and transient‐state kinetic methods. The reoxidation process involves minimally a second‐order interaction between reduced enzyme and oxygen leading to the formation of a spectrally modified enzyme intermediate, and a ...

Development of benzylamine oxidase and monoamine oxidase A and B in man
Biochemical Pharmacology, 1980Abstract We describe the widespread distribution of the enzymes benzylamine oxidase (BzAO) and monoamine oxidase A and B (MAO A, MAO B) in human tissues at three stages of development: fetal, neonatal and adult. Relatively low activity of each is present in fetal tissues, but the specific activities of BzAO and MAO B in fetal liver are similar to ...

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.

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 ...

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.

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.

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.

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 ...
