Application
Aconitase may be usefull in diabetes research as well as to study structural conservation between iron-responsive element binding proteins (IRE-BP) and isomerases .
Biochem/physiol Actions
Aconitase catalyses the stereo-specific isomerization of citrate to isocitrate via cis-aconitate in the tricarboxylic acid cycle. Aconitase is inhibited by cyanide, sulfide and copper and mercury at low concentrations. It is competitively inhibited by trans-aconitate. Aconitase contains an internal Fe-S cluster which is responsible for its activity.
Unit Definition
One unit will convert 1.0 μmole of citrate (via cis-aconitate) to isocitrate per min at pH 7.4 at 25 °C.

Organic acid content is regarded as one of the most important quality traits of fresh tomato (Solanum lycopersicum). However, the complexity of carboxylic acid metabolism and storage means that it is difficult to predict the best way to engineer altered

Diabetic neuropathy (DN) is the most common complication of diabetes and is characterized by distal-to-proximal loss of peripheral nerve axons. The idea of tissue-specific pathological alterations in energy metabolism in diabetic complications-prone tissues is emerging. Altered nerve metabolism in type

In many organisms, aconitases have dual functions; they serve as enzymes in the tricarboxylic acid cycle and as regulators of iron metabolism. In this study we defined the role of the aconitase AcnA in Streptomyces viridochromogenes Tü494, the producer of

Iron is required for nearly all organisms, playing important roles in oxygen transport and many enzymatic reactions. Excess iron, however, can be cytotoxic. Emerging evidence suggests that radioresistance can be achieved in lower organisms by the protection of proteins, but

There is no effective treatment for the cardiomyopathy of the most common autosomal recessive ataxia, Friedreich ataxia (FA). This disease is due to decreased expression of the mitochondrial protein, frataxin, which leads to alterations in mitochondrial iron (Fe) metabolism. The
