acriflavine (3,6-diaminoacridine) is an anticeptic drug developed in 1912. previous research has focused on investigation of the intercalating features of acriflavine, but little is known about its interaction with proteins. drug-receptor interaction is of major interest in clinical science. the aim of the present study was to evaluate the ability of acriflavine to induce alterations in conform...

Fourier transform infrared (FTIR) spectroscopy was employed to examine the thermal denaturation of the Fe(III), Fe(II), and Fe(II)-CO forms of cytochrome c peroxidase and horseradish peroxidase in phosphate buffer at pD 7.0. The amide I' regions of the deconvolved spectra are consistent with predominantly alpha-helical secondary structure around room temperature, but the alpha-helical absorptio...

Lignin peroxidase shares several structural features with the well-studied horseradish peroxidase and cytochrome c peroxidase but carries a higher redox potential. Here the heme domain of lignin peroxidase and the lignin peroxidase cyanide adduct was examined by 1HNMR spectroscopy, including nuclear Overhauser effect and two-dimensional measurements, and the findings were compared with those fo...

two peroxidases (ec. 1.11.1.7), pod i and pod ii were purified from the roots of cultivatedraphanus sativus l. var. cicil by one step ion-exchange chromatography after fractionation by acetone. the molecular weight of these enzymes were 43000 and 41000 daltons and rz 1.2 and 2.0 for pod i and pod ii, respectively. both enzymes consisted of a single polypeptide chain on sds-page. the maximum act...

A novel artificial peroxidase (AP) with highly catalytic efficiency was designed using hexadecyl trimethyl ammonium bromide (CTAB, 3 mM) nano-micelles and bovine heart cytochrome c (Cyt c, 0.5 µM) in 100 mM, pH 8.0 phosphate buffer at 25°C. The catalytic rate (kcat) and Michaelis-Menten (Km) of the AP were determined to be 0.311 ± 0.013 s(-1) and 8.64 ± 0.6 µM. The catalytic efficiency was 0.03...

Unlike lactoperoxidase and horseradish peroxidase, thyroid peroxidase catalyzed the oxidation of hydroquinone mostly by way of 2-electron transfer. This conclusion could be derived from three independent experiments: ESR measurements of p-benzosemiquinone, trapping the unpaired electron by cytochrome c, and spectrophotometric analysis of catalytic intermediates of the enzymes. The 1-electron fl...

We have solved the x-ray structures of the binary horseradish peroxidase C-ferulic acid complex and the ternary horseradish peroxidase C-cyanide-ferulic acid complex to 2.0 and 1.45 A, respectively. Ferulic acid is a naturally occurring phenolic compound found in the plant cell wall and is an in vivo substrate for plant peroxidases. The x-ray structures demonstrate the flexibility and dynamic c...
