Immunolocalization of steroidogenic enzymes in the vaginal mucous of Galea spixii during the estrous cycle. [PDF]

, 2017
BackgroundThe synthesis of sex steroids is controlled by several enzymes such as17α-hydroxylase cytochrome P450 (P450c17) catalyzing androgen synthesis and aromatase cytochrome P450 (P450arom) catalyzing estrogen synthesis, both of which must complex ...

Expression Levels of Enzymes Metabolizing an Anticancer Drug Ellipticine Determined by Electromigration Assays Influence its Cytotoxicity to Cancer Cells - A Comparative Study

International Journal of Electrochemical Science, 2014
The antineoplastic alkaloid ellipticine is a prodrug, of which the pharmacological efficiency is dependent on its cytochrome P450 (CYP)- and/or peroxidase-mediated activation to 12-hydroxy- and 13-hydroxyellipticine, which are both the metabolites ...

Peroxidase Activity of Cytochrome c [PDF]

Bulletin of the Korean Chemical Society, 2004
, deferoxamine (DFX)and ethylenediamine tetraacetic acid (EDTA) were pur-chased from Sigma. The diammonium salt of 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulfonate) (ABTS) was obtainedfrom Boehringer Mannheim. Chelex 100 resin (sodiumform) was obtained from Bio-Rad. All materials weretreated with Chelex 100 resin.

Multi-heme Cytochromes in Shewanella oneidensis MR-1:Structures, functions and opportunities [PDF]

, 2015
Multi-heme cytochromes are employed by a range of microorganisms to transport electrons over distances of up to tens of nanometers. Perhaps the most spectacular utilization of these proteins is in the reduction of extracellular solid substrates ...

Peroxidase Activity of Human Hemoproteins: Keeping the Fire under Control

Molecules, 2018
The heme in the active center of peroxidases reacts with hydrogen peroxide to form highly reactive intermediates, which then oxidize simple substances called peroxidase substrates.
