Hematoporphyrin is a intermediate product in haemachrome synthesize in normal human body. It can selectively accumulate in tumor tissue and be reserved for a long time. 血卟啉在正常人体中为线粒体酶系催化乙酸和甘氨酸合成血红素的中间产物,在肿瘤组织中选择性聚积并能够长时间潴留。
Protoporphyrinogen oxidase ( Protox, EC 1.3.3.4), the key enzyme in chlorophylls and haemachrome biosynthesis, has been identified as the important target site of action for several herbicides. 原卟啉原氧化酶(Protox)是叶绿素和血红素生物合成中的一个关键酶,是除草剂的重要靶标。
