Uroporphyrinogen-III C-methyltransferase (, ''uroporphyrinogen methyltransferase'', ''uroporphyrinogen-III methyltransferase'', ''adenosylmethionine-uroporphyrinogen III methyltransferase'', ''S-adenosyl-L-methionine-dependent uroporphyrinogen III methylase'', ''uroporphyrinogen-III methylase'', ''SirA'', ''CysG'', ''uroporphyrin-III C-methyltransferase'', ''S-adenosyl-L-methionine:uroporphyrin-III C-methyltransferase'') is an enzyme with system name ''S-adenosyl-L-methionine:uroporphyrinogen-III C-methyltransferase''. This enzyme catalyses the following chemical reaction : 2 S-adenosyl-L-methionine + uroporphyrinogen III 2 S-adenosyl-L-homocysteine + precorrin-2 (overall reaction) :(1a) S-adenosyl-L-methionine + uroporphyrinogen III S-adenosyl-L-homocysteine + precorrin-1 :(1b) S-adenosyl-L-methionine + precorrin-1 S-adenosyl-L-homocysteine + precorrin-2 Uroporphyrinogen-III C-methyltransferase catalyses two methylation reactions, the first forming precorrin-1 and the second leading to the formation of precorrin-2. == 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「Uroporphyrinogen-III C-methyltransferase」の詳細全文を読む スポンサード リンク
