In enzymology, a coproporphyrinogen dehydrogenase () is an enzyme that catalyzes the chemical reaction :coproporphyrinogen III + 2 S-adenosyl-L-methionine protoporphyrinogen IX + 2 CO2 + 2 L-methionine + 2 5'-deoxyadenosine Thus, the two substrates of this enzyme are coproporphyrinogen III and S-adenosyl-L-methionine, whereas its 4 products are protoporphyrinogen IX, CO2, L-methionine, and 5'-deoxyadenosine. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with other acceptors. The systematic name of this enzyme class is coproporphyrinogen-III:S-adenosyl-L-methionine oxidoreductase (decarboxylating). Other names in common use include oxygen-independent coproporphyrinogen-III oxidase, HemN, radical SAM enzyme, and coproporphyrinogen III oxidase. This enzyme participates in porphyrin and chlorophyll metabolism. ==References== * * 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Coproporphyrinogen dehydrogenase」の詳細全文を読む スポンサード リンク
