The strigolactone (SL) receptor in plants is unusual in that it both binds and hydrolyses SL molecules. Landmark studies had proposed that a product of hydrolysis irreversibly binds the receptor and then activates signalling. However, recent breakthrough articles (Seto et al. Nat. Commun. 2019;10:191 and Shabek et al. Nature 2018;563:652-656) have revealed a new model based on inhibition of hydrolysis by protein conformation.
在植物中，独脚金内酯（SL）受体很特别，因为它既能结合又能水解 SL 分子。具有里程碑意义的研究曾提出，水解的产物不可逆地结合受体，然后激活信号转导。然而，最近的突破性文章（Seto 等人，《自然通讯》2019；10：191 和 Shabek 等人，《自然》2018；563：652-656）揭示了一个基于蛋白构象抑制水解的新模型。
