Sulfite sensitivity and sulfite oxidase actiivty inDrosophila melanogaster

Biochemical Genetics, 1993
The relationship between sulfite oxidase (SO) and sulfite sensitivity in Drosophila melanogaster is addressed. Significant improvements to the SO assay have provided an investigative tool which can be applied to further studies of this molybdoenzyme. Using the second-instar larval stage of D, melanogaster, we have shown a direct relationship between ...

Mediated, anaerobic voltammetry of sulfite oxidase

Analytical Chemistry, 1990
The anaerobic voltammetry of the Mo/Fe enzyme, sulfite oxidase (SO), is described for the mediators cytochrome c, [Ru(NH3)6]3+/2+, TMPD+/0, and [Co(bpy)3]3+/2+. Theory derived for steady-state voltammetric catalysis correctly predicts the observed concentration and scan-rate dependencies of the catalytic waves.

Sulfite determination: Sulfite oxidase

1987
Publisher Summary This chapter discusses the sulfite determination. Sulfite and sulfite adducts—for example, aldehyde-bisulfite addition compounds—are distributed in very low concentrations in plants and animals. Their physiological importance is unknown.

Radiation inactivation of hepatic sulfite oxidase

Archives of Biochemistry and Biophysics, 1987
Sulfite oxidase (EC 1.8.3.1), purified from chicken liver, is comprised of two identical subunits of 55 kDa, each of which contains a molybdenum and heme prosthetic group. The functional size of sulfite oxidase was determined by radiation inactivation analysis using both full, sulfite:cytochrome c reductase, and partial, sulfite:ferricyanide reductase,

Sulfite oxidase from Merluccius productus

Biochimica et Biophysica Acta (BBA) - Enzymology, 1980
Sulfite oxidase (sulfite:oxygen oxidoreductase, EC 1.8.3.1) was purified 482-fold from liver of the Pacific hake Merluccius productus. The molecular weight of the enzyme was found to be 120 000 by gel exclusion chromatography on Sephadex G-100. Electrophoretic analysis on sodium dodecyl sulfate (SDS)-polyacrylamide gel revealed that the enzyme was ...

Measurement of Sulfite Using Sulfite Oxidase and Luminol Chemiluminescence

Analytical Communications, 1997
Measurement of sulfite using sulfite oxidase and luminol chemiluminescence was performed. Sulfite oxidase from chicken liver was immobilized in a reactor column filled with polysaccharide gel beads. The effects of buffer solution, hydrogen peroxide concentration and sulfite concentration on the chemiluminescence intensity were examined.

Neurologic Injury in Isolated Sulfite Oxidase Deficiency

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 2014
Background:We review clinical, neuroimaging, and genetic information on six individuals with isolated sulfite oxidase deficiency (ISOD).Methods:All patients were examined, and clinical records, biochemistry, neuroimaging, and sulfite oxidase gene (SUOX) sequencing were reviewed.Results:Data was available on six individuals from four nuclear families ...

Molecular cloning of human liver sulfite oxidase

Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1995
A 2.4 kilobase cDNA clone of human sulfite oxidase was isolated from a human liver cDNA library in lambda gt10. Comparison of three sulfite oxidase sequences to several plant and fungal nitrate reductase sequences reveals a single conserved cysteine with highly conserved flanking sequences.

Oxygen reactivity of mammalian sulfite oxidase provides a concept for the treatment of sulfite oxidase deficiency

Biochemical Journal, 2015
Mammalian sulfite oxidase (SO) is a dimeric enzyme consisting of a molybdenum cofactor- (Moco) and haem-containing domain and catalyses the oxidation of toxic sulfite to sulfate. Following sulfite oxidation, electrons are passed from Moco via the haem cofactor to cytochrome c, the terminal electron acceptor.
