In enzymology, a precorrin-4 C11-methyltransferase () is an enzyme that catalyzes the chemical reaction :S-adenosyl-L-methionine + precorrin-4 S-adenosyl-L-homocysteine + precorrin-5 Thus, the two substrates of this enzyme are S-adenosyl methionine and precorrin 4, whereas its two products are S-adenosylhomocysteine and precorrin 5. This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:precorrin-4 C11 methyltransferase. Other names in common use include precorrin-3 methylase, and CobM. This enzyme participates in porphyrin and chlorophyll metabolism. ==Structural studies== As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and . 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「Precorrin-4 C11-methyltransferase」の詳細全文を読む スポンサード リンク
