Phylloquinol (the quinol form of vitamin K1) is synthesized from 2-phytyl-1,4-naphthoquinol and S-adenosylmethionine at the thylakoid membranes of spinach chloroplasts. The addition of soluble stroma protein (chloroplast extract) is necessary S-Adenosylhomocysteine acts as strong competitive inhibitor.
叶绿素(维生素 K1 的羟基形式)是由 2-phytyl-1,4-naphthoquinol 和 S-腺苷甲硫氨酸在菠菜叶绿体的类囊体膜上合成的。添加可溶性基质蛋白(叶绿体提取物)是必要的 S-腺苷高半胱氨酸作为强竞争性抑制剂。
