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 have been solved for this class of enzymes, with PDB PDB may refer to: * Chess Problem Database Server (PDB Server) * 1,4-Dichlorobenzene (paradichlorobenzene) * Party of German-speaking Belgians, (German: '), a political party and predecessor of the ProDG * PDB (Palm OS), a container format for reco ... accession codes , , , , , , , , , , , and .

Arsenate Reductase (azurin)
Arsenate reductase (azurin) () is an enzyme that catalyzes the chemical reaction :arsenite + H2O + 2 azurinox \rightleftharpoons arsenate + 2 azurinred + 2 H+ The 3 substrates of this enzyme are arsenite, water, and oxidised azurin, whereas its 3 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 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 Fe-4Scluster and a Rieske-type Fe-2Scluster. Also uses a c-type cytochrome Cytochromes are redox-active proteins containing a heme, with a central Fe atom at its core, as a cofactor. They are involved in electron transport ...
