Novel SUOX mutations were detected in 3 Sulfite oxidase deficiency cases
Nitrite binds and reduces at the molybdenum site of mammalian sulfite oxidase, which may be allosterically regulated by heme and molybdenum domain interactions, and contributes to the mammalian nitrate-nitrite-NO signaling pathway in human fibroblasts.
This finding suggests the possibility to use oxygen-reactive SO variants in sulfite detoxification, as the loss of SO activity is causing severe neurodegeneration
Several mutants of H304 and R309 of SUOX were investigated by steady-state kinetics, laser flash photolysis studies of intramolecular electron transfer (IET), and spectroelectrochemistry.
SUOX was decreased and AKR1B10 (show AKR1B10 ELISA Kits) and CD34 (show CD34 ELISA Kits) were increased with the stepwise progression of hepatocarcinogenesis.
combined genetic association studies in women from China/Netherlands/United States: Data suggest that an SNP in SUOX locus (rs705702) and SNPs in other proteins are associated with polycystic ovary syndrome across ethnic differences. [META-ANALYSIS]
In this study a human sulfite oxidase variant, in which the active site has been modified to alter substrate specificity and activity from sulfite oxidation to nitrate reduction, is compared to chicken sulfite oxidase.
prepared and purified samples of the wild type and various mutants of human SO that are depleted of chloride. These samples do not exhibit the typical lpH (show LCT ELISA Kits) EPR (show EREG ELISA Kits) spectrum at low pH but rather exhibit spectra that are characteristic of the blocked species
Experimental deletions of nonconserved amino acids in the 14-residue interdomain polypeptide tether of sulfite oxidase shorten its length and result in more drastically reduced intramolecular electron transfer rate constants.
Sulfite oxidase gene expression in brain and in other tissues.
A single base insertion leading to a premature stop codon in the SUOX is associated with the arachnomelia phenotype.
the significance of sulfite oxidase for the overall shoot response to SO2 in relation to alterations in plant phenology and physiology
In contrast to chicken sulfite oxidase (SO), Arabidopsis SO crystallizes without a sulfate bound in the active site.
structural analysis of the Mo(V) forms of sulfite oxidase from Arabidopsis thaliana
Could be responsible for removing sulfite as a toxic metabolite, which might represent a means to protect the cell against excess of sulfite derived from SO2 gas in the atmosphere (acid rain) or during the decomposition of sulfur-containing amino acids.
AtSO is expressed mainly in the green tissues/organs in a light-dependent way
The isotropic hfi constant of 33S determined in these experiments was about 3 MHz, which demonstrates the presence of coordinated sulfate in the sulfite-reduced low-pH form of the plant enzyme.
Sulfite oxidase is a homodimeric protein localized to the intermembrane space of mitochondria. Each subunit contains a heme domain and a molybdopterin-binding domain. The enzyme catalyzes the oxidation of sulfite to sulfate, the final reaction in the oxidative degradation of the sulfur amino acids cysteine and methionine. Sulfite oxidase deficiency results in neurological abnormalities which are often fatal at an early age. Alternative splicing results in multiple transcript variants encoding identical proteins.
