peroxidase isoenzyme/brassica

We have purified various peroxidase isoenzymes from roots and hairy-root cultures of turnip (Brassica napus) which could potentially be used for commercial applications such as an enzyme immunoassays, diagnostic test kits, wastewater treatment and soil remediation. One of them, a basic peroxidase

A highly specific rabbit antiserum raised against peroxidase (PRXa) from petunia (Petunia hybrida) was used to investigate the antigenic relatedness of peroxidases in the Solanaceae. After SDS-PAGE of crude leaf extracts from a large number of species of this family, immunoblotting revealed that

Simple reproducible procedures for purification of the main soluble (S) and ionically bound (IB) cationic peroxidase isoenzymes from turnip roots were established. The procedures included ammonium sulfate precipitation of the isoenzymes, chromatographic separation of the main isoenzymes using

Proton NMR spectra at 270 MHz have been measured for horseradish peroxidase and turnip peroxidase isoenzymes (P1, P2, P3 and P7) in both their high spin ferric native states and as the low spin ferric cyanide complexes. Resonances of amino acids near the heme have been identified and used to

Antisera specific for the basic peroxidase from horseradish (Amoracea rusticana) were used to examine homology among horseradish peroxidase isoenzymes and among basic peroxidases from root plants. The antisera cross-reacted with all tested isoperoxidases when measured by both agar diffusion and

Three turnip peroxidases (fractions C1, C2, and C3) were partially purified and characterized, to permit study of their feasibility for use in clinical and enzyme immunoassays. These fractions represented 20% of the initial activity, and fractions C1 and C2 were purified to homogeneity. The optimum

Phenolic compounds present in the drainage from several industries are harmful pollutants and represent a potential danger to human health. In this work we have studied the removal of phenol from water using Brassica napus hairy roots as a source of enzymes, such as peroxidases, which were able to

A new gene, designated as BnPrx (GenBank Accession No. DQ078754), was isolated from oilseed rape (Brassica napus) by SMART Rapid Amplification of cDNA Ends (RACE). The full-length cDNA is 1307 bp long and contains a 1062 bp open reading frame (ORF), which encodes a 354 amino acid peroxidase
