胆固醇的生物合成发生在内质网(ER)。从水溶性的小代谢物,通过越来越复杂的中间体,到水不溶性胆固醇,它像乐高一样的结构需要许多不同的酶。相关酶的功能障碍可导致几种人类先天缺陷和疾病。在这里,我们回顾了最近三种关键的胆固醇生物合成酶的结构:角鲨烯环氧化酶(SQLE), NAD(P)依赖性类固醇脱氢酶样(NSDHL)和3β-羟基类固醇Δ8-Δ7异构酶称为EBP。此外,我们还讨论了酰基辅酶a的结构:胆固醇酰基转移酶(ACAT)酶,它负责从胆固醇形成胆固醇酯,以维持内质网中的胆固醇稳态。这些酶的结构揭示了它们的催化机制,并为开发治疗与它们失调有关的疾病的药物提供了分子基础。
Cholesterol biosynthesis occurs in the endoplasmic reticulum (ER). Its lego-like construction from water-soluble small metabolites via intermediates of increasing complexity to water-insoluble cholesterol requires numerous distinct enzymes. Dysfunction of the involved enzymes can cause several human inborn defects and diseases. Here, we review recent structures of three key cholesterol biosynthetic enzymes: Squalene epoxidase (SQLE), NAD(P)-dependent steroid dehydrogenase-like (NSDHL), and 3β-hydroxysteroid Δ8-Δ7 isomerase termed EBP. Moreover, we discuss structures of acyl-CoA:cholesterol acyltransferase (ACAT) enzymes, which are responsible for forming cholesteryl esters from cholesterol to maintain cholesterol homeostasis in the ER. The structures of these enzymes reveal their catalytic mechanism and provide a molecular basis to develop drugs for treating diseases linked to their dysregulation.
