Fsa 2和Phm 7是一对独特的周环酶,催化木贼素和phomasetin的生物合成中的[4 + 2]环加成反应,具有反向立体选择性,这两种化合物都是HIV-1整合酶的有效抑制剂。在这里,我们解决了Fsa 2和Phm 7的晶体结构,这两个都具有不寻常的“双β桶”折叠。Fsa 2和Phm 7的活性位点之间存在明显的不同残基,建模实验提供了确定反向立体选择性的关键结构信息。这些结果为理解天然周环酶如何控制催化立体选择性提供了理论依据,也为蛋白质工程的进一步研究提供了理论依据。
Fsa2 and Phm7 are a unique pair of pericyclases catalyzing [4 + 2] cycloaddition reactions with reverse stereoselectivities in the biosynthesis of equisetin and phomasetin, both of which are potent HIV-1 integrase inhibitors. We here solve the crystal structures of Fsa2 and Phm7, both of which possess unusual “two-β barrel” folds. Different residues are evident between the active sites of Fsa2 and Phm7, and modeling experiments provide key structural information determining the reverse stereoselectivities. These results provide a better understanding of how natural pericyclases control the catalytic stereoselectivities and benefit the protein engineering in future.
