Catechol oxidase — structure and activity

Anion coordination selective [Mn3] and [Mn4] assemblies: synthesis, structural diversity, magnetic properties and catechol oxidase activity.

Syntheses, crystal structures, magnetic properties and catechol oxidation behavior are presented for [Mn3] and [Mn4] aggregates, [MnMn(II)(O2CMe)4(dmp)2(H2O)2]·2H2O (1·2H2O), [MnMn(II)(O2CCH2Cl)4(dmp)2(H2O)2]·H2O·MeOH (2·H2O·MeOH), [Mn(μ3-O)(dmp)4(μ-DMSO)(N3)(DMSO)(H2O)]ClO4·DMSO (3·ClO4·DMSO), and [Mn(μ3-O)(dmp)4(μ-DMSO)(ClO4)(DMSO)(H2O)]ClO4·DMSO (4·ClO4·DMSO), developed with single type liga...

The behaviour of secondary and tertiary amines in the presence of catechol and belladonna catechol oxidase.

Catechol-o-methyl Transferase and Monoamine Oxidase Activity in the Ocular Tissues of Albino Rabbits.

The distribution of catechol-O-methyl transferase and monoamine oxidase activity in the ocular tissues of albino rabbits has been determined with a radioactive tracer assay. The distribution of the former varied in the different tissues within a restricted range whereas the distribution of monoamine oxidase activity exhibited larger variations. Sympathetic denervation did not appear to affect c...

Catechol oxidase activity of di-Cu2+-substituted aminopeptidase from Streptomyces griseus.

Streptomyces griseus aminopeptidase exhibits activities toward the hydrolyses of peptides and bis(p-nitrophenyl)phosphate (40 billion fold) and catechol oxidation reported herein with catalytic efficiency (kcat/Km) only about 10 times smaller than that of gypsywort catechol oxidase. The multifunctionality of this enzyme suggests that it is a unique system for further exploration of protein stru...

The action of inhibitors on the catechol oxidase of potatoes.

ATTEMPTS have been made to classify the phenolases into groups such as the catechol oxidases, tyrosinases, and laccases [Raper, 1928], but the classification is made difficult by the lack of satisfactory methods of characterising the enzymes [Onslow and Robinson, 1928]. The present work was undertaken with the object of testing whether the catechol oxidases of different origin behave similarly ...
