With the use of the cytochemical stain for horseradish peroxidase of Graham and Karnovsky (1966. J. Histochem. Cytochem.14:291), conjugates of horseradish peroxidase with ricin, wheat germ agglutinin, and phytohemagglutinin were employed for the morphologic demonstration of d-galactose (ricin), N-acetylglucosamine (wheat germ), and N-acetylgalactosamine (phytohemagglutinin) containing moieties ...

"Specific granule" deficiency (SGD) has been previously associated with lactoferrin deficiency. The antimicrobial peptides termed defensins, comprising 30% of normal primary granule proteins, have also been shown to be markedly deficient in SGD. The present study was undertaken to correlate these findings with ultrastructural morphometric analysis and peroxidase cytochemistry. Peroxidase-positi...

The genomes of three representative Polyporales (Bjerkandera adusta, Phlebia brevispora and a member of the Ganoderma lucidum complex) were sequenced to expand our knowledge on the diversity of ligninolytic and related peroxidase genes in this Basidiomycota order that includes most wood-rotting fungi. The survey was completed by analyzing the heme-peroxidase genes in the already available genom...

De novo proteins from designed combinatorial libraries were bound to heme terminated gold electrodes. The novel heme proteins were shown to possess peroxidase activity, and this activity was compared to that of horseradish peroxidase and bovine serum albumin when immobilized in a similar fashion. The various designed proteins from the libraries displayed distinctly different levels of peroxidas...
