Cationic peanut peroxidase was used for the first time for the determination of phenols at a level of 0.5–10μM. The examined phenols were found to be inhibitors or second substrates of peanut peroxidase in the indicator reaction of the oxidation o

Plant peroxidases are composed of a peptide and associated heme, calcium and glycans. The 3D structure of the major cationic peanut peroxidase has revealed the sites of the heme and calcium. But the diffraction of the glycans was not sufficient to sh

Cationic peanut peroxidase has three N-linked glycans. Two glycoforms, CP− and CP+, are known to occur. In this study, the glycans of CP− and CP+ were sequentially separated and identified by trypsin digestion, Bio-Gel P-6 filtration, and reverse

During the normal growth cycle of peanut (Arachis hypogaea L.) cells, cultured in suspension medium, cell aggregates of 0.5 mm during late growth phase. Calmodulin rose to its original level during 0.5 but not of the

In vitro experiments show that anionic peroxidase has a higher affinity for both ascorbic acid and IAA and a greater Vmax than cationic peroxidase in the oxidation reaction with the presence of H2O2. The peanut hypocotyls cultured in a medium with do

Alterations of isoperoxidases were studied in 1.0 cm segments from 3-day-peanut-seedling (Arachis hypogaea L.) hypocotyls as they were cultured on Linsmayer and Skoog (LS) medium with or without the addition of 5 mM meta-fluoro-tyrosine (MFT). The al

A comparative study on tyrosine oxidation was made with a pure cationic and anionic peroxidase from peanut cell culture medium. The results showed that both isozymes possessed almost identical capacity to oxidize tyrosine to dityrosine, isodityrosine

Two monoclonal antibodies (46-12-C12 and 23-6-C12) raised against anionic peanut peroxidase were found to have independent epitope sites. These topographic sites were found to be located within a tryptic glycopeptide (Atgp) from the anionic isozyme b

We have isolated, cloned, and characterized two cDNAs corresponding to the mRNAs for cationic peroxidases synthesized by cultured peanut cells. The first clone was obtained from a phage lambda gt11 library screened with antibodies directed against th

A cationic and an anionic peanut peroxidase were isolated to purity as shown by 2D electrophoresis. Amino acid analysis offered evidence for differences. Variations between the isozymes were also noted in a slight difference in the heme absorption ma
