Chronic granulomatous disease (CGD) is a disorder of host defense due to genetic defects of the superoxide (O2-) generating NADPH oxidase in phagocytes. A membrane-bound cytochrome b558, a heterodimer consisting of gp91-phox and p22-phox, is a critic

The putative role of singlet oxygen (1O2) in the respiratory burst of neutrophils has remained elusive due to the lack of reliable means to study its quantitative production. To measure 1O2 directly from biological or chemical reactions in the near i

A membrane-bound cytochrome b558, a heterodimer consisting of gp91-phox and p22-phox, is a critical component of the superoxide (O2-)-generating reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase in phagocytes. Chronic granulomatous

— We report the detection of a weak near-infrared light emission originating from 8 nM singlet molecular oxygen (1O2) produced in a mixture of 1 mM hypochlorite (OC1-) and 8 nM hydrogen peroxide (H2O2). The measurements were made with a highly sens

BACKGROUND Chronic granulomatous disease (CGD) is an inherited disease characterized clinically by severe recurrent bacterial infections from infancy. This disease is a disorder of the formation of superoxide (O2-) by the neutrophil NADPH oxidase sys

The combination of electron paramagnetic resonance (EPR), near-infrared magnetic circular dichroism (NIR-MCD) and resonance Raman (RR) spectroscopies at cryogenic temperatures has been used to identify the axial heme ligation of the low spin cytochro

Cytochrome b558 purified from pig neutrophils was studied to characterize the spin state of the heme iron in relation to its O2-. generating activity. ESR spectra of cytochrome b558 either from resting or stimulated neutrophils showed a low-spin hemo

The in vitro formation of phenylhydronitroxide and 2-methylphenylhydronitroxide free radicals from nitrosobenzene (NB) and 2-nitrosotoluene (NT), respectively, in either red blood cells (RBC) or RBC hemolysates, was confirmed by electron spin resonan

Cytochrome b558 of pig blood neutrophils was purified from the membranes of resting cells to examine its ability to reconstitute superoxide (O2-)-forming NADPH oxidase activity in a cell-free assay system containing cytosol and fatty acid. The membra

Low-temperature electron paramagnetic resonance (EPR) spectrometry on granulocytes prepared from pig blood was carried out with concentrated cellular and subcellular fractions to characterize EPR signals of cytochrome b-558 (cyt b-558). A thick cell
