Arsenate Reductase (glutaredoxin)
Arsenate reductase (glutaredoxin) () is an enzyme that catalyzes the chemical reaction :arsenate + glutaredoxin \rightleftharpoons arsenite + glutaredoxin disulfide + H2O Thus, the two substrates of this enzyme are arsenate and glutaredoxin, whereas its 3 products are arsenite, glutaredoxin disulfide, and water. This enzyme belongs to the family of oxidoreductases, specifically those acting on phosphorus or arsenic in donor with disulfide as acceptor. The systematic name of this enzyme class is glutaredoxin:arsenate oxidoreductase. Structural studies As of late 2007, 12 structures A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized.

Arsenate Reductase (azurin)
Arsenate reductase (azurin) () is an enzyme that catalysis, catalyzes the chemical reaction :arsenite + H2O + 2 azurinox \rightleftharpoons arsenate + 2 azurinred + 2 H+ The 3 substrate (biochemistry), substrates of this enzyme are arsenite, water, and oxidised azurin, whereas its 3 product (chemistry), products are arsenate, reduced azurin, and hydrogen ion. Classification This enzyme belongs to the family of oxidoreductases, specifically those acting on phosphorus or arsenic in donor with a copper protein as acceptor. Nomenclature The List of enzymes, systematic name of this enzyme class is arsenite:azurin oxidoreductase. This enzyme is also called arsenite oxidase. Structure and function The enzyme contains a molybdopterin centre comprising two molybdopterin guanosine dinucleotide cofactors bound to molybdenum, a Iron-sulfur protein, [3Fe-4S] cluster and a Rieske protein, Rieske-type [2Fe-2S] cluster. Also uses a c-type cytochrome or as acceptors. References * * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
