氧化酶催化植物代谢中的许多不同反应。在这套酶中有2-酮戊二酸/Fe(II)依赖性双加氧酶(2-ODD)。细胞色素P450(CYP)通常被认为是自然界中最通用的氧化酶,但2-ODD催化反应的多样性和复杂性上级CYP。由2-ODD催化的氧化反应的列表包括羟基化、去甲基化、去饱和、闭环、开环、差向异构化、重排、卤化和去亚甲基化。此外,最近的工作,包括发现2-ODD参与表观遗传调控,以及其他催化专门代谢途径中的几个特征步骤,支持2-ODD是最通用和最重要的氧化生物催化剂的论点。本文综述了2-ODDs催化的几个关键反应,并讨论了这些酶在植物代谢中的意义和作用。
Oxidative enzymes catalyze many different reactions in plant metabolism. Among this suite of enzymes are the 2-oxoglutarate/Fe(II)-dependent dioxygenases (2-ODDs). Cytochromes P450 (CYPs) as often considered the most versatile oxidative enzymes in nature, but the diversity and complexity of reactions catalyzed by 2-ODDs is superior to the CYPs. The list of oxidative reactions catalyzed by 2-ODDs includes hydroxylations, demethylations, desaturations, ring closure, ring cleavage, epimerization, rearrangement, halogenation, and demethylenation. Furthermore, recent work, including the discovery of 2-ODDs involved in epigenetic regulation, and others catalyzing several characteristic steps in specialized metabolic pathways, support the argument that 2-ODDs are among the most versatile and important oxidizing biological catalysts. In this review, we survey and summarize the pertinent literature with a focus on several key reactions catalyzed by 2-ODDs, and discuss the significance and impact of these enzymes in plant metabolism.
