产品内容
本酶催化的反应为Abieta-7,13-Dien-18-Ol + 2 [Reduced NADPH---Hemoprotein Reductase] + 2 O2 = Abieta-7,13-Dien-18-Oate + 2 [Oxidized NADPH---Hemoprotein Reductase] + 3 H2O (Overall Reaction);;(1a) Abieta-7,13-Dien-18-Ol + [Reduced NADPH---Hemoprotein Reductase] + O2 = Abieta-7,13-Dien-18,18-Diol + [Oxidized NADPH---Hemoprotein Reductase] + H2O;;(1b) Abieta-7,13-Dien-18,18-Diol = Abieta-7,13-Dien-18-Al + H2O (Spontaneous);;(1c) Abieta-7,13-Dien-18-Al + [Reduced NADPH---Hemoprotein Reductase] + O2 = Abieta-7,13-Dien-18-Oate + [Oxidized NADPH---Hemoprotein Reductase] + H2O，系统名称为Abieta-7,13-Dien-18-Ol,[reduced NADPH---Hemoprotein Reductase]:oxygen Oxidoreductase (18-Hydroxylating)，一种细胞色素 P-450（血红素-硫醇盐）蛋白。该酶催化松香酸生物合成途径中的一步。该活性已在巨大冷杉（Abies grandis）和扭叶松（Pinus contorta）的无细胞茎提取物中得到证实 [1]，且编码该酶的基因已在火炬松（Pinus taeda）中被鉴定 [3]。重组酶可催化多种二萜醇和二萜醛的氧化，包括左旋海松二烯醇、异海松-7,15-二烯醇、异海松-7,15-二烯醛、脱氢松香二烯醇和脱氢松香二烯醛。它不能氧化松香二烯。
