Intramolecular Oxidoreductases

Medical Definition: Enzymes of the isomerase class that catalyze the oxidation of one part of a molecule with a corresponding reduction of another part of the same molecule. They include enzymes converting aldoses to ketoses (ALDOSE-KETOSE ISOMERASES), enzymes shifting a carbon-carbon double bond (CARBON-CARBON DOUBLE BOND ISOMERASES), and enzymes transposing S-S bonds (SULFUR-SULFUR BOND ISOMERASES). (From Enzyme Nomenclature, 1992) EC 5.3.
CAS Number: EC 5.3
Intramolecular Oxidoreductases Categories.
Canadian Medical Guide Definition Aldose-Ketose Isomerases - Enzymes that catalyze the interconversion of aldoses and ketoses. EC 5.3.1.
Canadian Medical Guide Definition Carbon-Carbon Double Bond Isomerases - Enzymes that catalyze the shifting of a carbon-carbon double bond from one position to another within the same molecule. EC 5.3.3.
Canadian Medical Guide Definition Sulfur-Sulfur Bond Isomerases - Enzymes that catalyze the transposition of a sulfur-sulfur bond. EC 5.3.4.
Canadian Medical Guide Definition Thromboxane-A Synthase - An enzyme found predominantly in platelet microsomes. It catalyzes the conversion of PGG(2) and PGH(2) (prostaglandin endoperoxides) to thromboxane A2. EC 5.3.99.5.
