To learn more about this reaction, which could potentially proceed through a Diels-Alder mechanism, we determined the 1.50-A-resolution crystal structure of SpnF bound to S-adenosylhomocysteine. This sets the stage for advanced experimental and computational studies to determine the precise mechanism of SpnF-mediated cyclization. The structure of SpnF, a standalone enzyme that catalyzes [4 + 2] cycloaddition.,Fage CD, Isiorho EA, Liu Y, Wagner DT, Liu HW, Keatinge-Clay AT Nat Chem Biol. 2015 Mar 2. doi: 10.1038/nchembio.1768.
