Enzyme sources for urinary oxalate measurements
An alternative source of oxalate oxidase (Oxox) was to be purified for use in a biosensor system to detect oxalate in patients suffering from primary hyperoxaluria (PH). Oxox has been isolated from a number of sources, however there is significant variation in the information available. Prior to …

Probing the Mechanism of Oxalate Decarboxylase
Oxalate decarboxylase (EC 4. 1. 1. 2 OxDC) from Bacillus subtilis is a manganese-dependent enzyme that catalyzes the cleavage of the chemically inactive C-C bond in oxalate to yield formate and carbon dioxide. A mechanism involving Mn(III) has been proposed for OxDC, however no clear spectroscopic …

Hydrogen Peroxide Inhibition and Inactivation of Bicupin Oxalate Oxidase
<p>Oxalate oxidase is a manganese containing enzyme that catalyzes the oxygen dependent oxidation of oxalate to carbon dioxide and hydrogen peroxide. Oxalate oxidase from <em>Ceriporiopsis subvermispora</em> (CsOxOx) is the first characterized bicupin oxalate oxidase. Potential applications of …

Crystallization of calcium oxalate on molecularly imprinted polymer surfaces
Calcium oxalate (CaOx) is the most common component of human kidney stones. Heterogeneous nucleation is regarded as the key mechanism in this process. As such, crystallization of this substance has been studied in several different model systems. However, molecular imprinting has not been …

Isothermal Titration Calorimetry Uncovers Substrate Promiscuity of Bicupin Oxalate Oxidase
<p>Oxalate oxidase from <em>Ceriporiopsis subvermispora</em> (CsOxOx) is a manganese-dependent enzyme that catalyzes the oxygen-dependent oxidation of oxalate to form two moles of carbon dioxide and one mole of hydrogen peroxide. CsOxOx is the first oxalate oxidase reported to have a two beta …

Inhibition of Calcium Oxalate Monohydrate Crystallization Using Organic Growth Modifiers
Inhibition of calcium oxalate monohydrate (COM), the most common component in human kidney stone diseases, was investigated using various structural derivatives of citrate, a known inhibitor of COM crystallization. Bulk crystallization studies revealed the specific binding of modifiers to COM …

Impacts of Salinity on Germination, Growth, Oxalate and Inorganic Ion Relations
… number of kochia populations. Kochia accumulated oxalate in all plant parts, with highest levels in mature leaves and lowest in roots, and intermediate levels in young leaves and stems. Water-soluble oxalate levels exceeding the safe limits for ruminants were found in mature leaves. Leaf oxalate …

Oxalate nephrosis in a population of South Australian koalas (Phascolarctos cinereus).
… unclear. Kidney crystals consistent with calcium oxalate had been observed in several koalas, suggesting that oxalate nephrosis may occur. The aims of this study were to describe renal pathological changes and confirm oxalate deposition in these koalas and also to investigate possible causes of …

ANALYSIS OF ANIONS AND PROTEINS RELATED TO OXALATE METABOLISM IN HUMAN ERYTHROCYTES
The metabolism of oxalate and its related anions in human erythrocytes have not been previously studied in detail. In this study, we identified the presence and investigated the functional role of glyoxylate reductase/hydroxypyruvate reductase GR/HPR), a key protein in the metabolism of oxalate, in …

Structures of oxalate oxidoreductase : C₂ activation by a microbial TPP-dependent ferredoxin oxidoreductase
… arthritis. Current strategies to mitigate oxalate toxicity focus on diet management, though recent therapeutic studies have begun to focus on both probiotic as well as enzymatic treatments for the prevention of oxalate-related illnesses. The acetogenic bacterium Moorella thermoacetica has …

Oxalate content of green juices and strategies for reduction of soluble oxalate content : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… Unfortunately, the risks of developing acute oxalate nephropathy is high following the consumption of some green juices and fruit juices. This study investigates the occurrence and levels of oxalates in green juices made from common fruit and vegetables available in New Zealand. The influence …

Equilibrium Study of the Three Component System Oxalic Acid — Sodium Oxalate — Water at 25°
The experimental measurement of chemical equilibria frequently presents problems of considerable difficulty. In some cases the position of equilibrium may be such that the reaction goes nearly to completion in one direction, resulting in an extremely small concentration of one or more of the …

A study of the growth and aggregation of calcium oxalate monohydrate / by Allan Sidney Bramley.
… of the growth and aggregation of calcium oxalate mono-dydrate in metastable saline solutions using batch and continuous systems. The physical chemistry of calcium oxalate mono-hydrate in aqueous solutions is considered. A tubular crystalliser to be used as an in vitro system is described.
