Loop 482–492 (green) adopts an “out” conformation in abietadiene synthase, whereas the corresponding loop of ent-copalyl diphosphate synthase adopts an “in” conformation. The “out” conformation of this loop may be required for productive substrate binding. Originally published in ref (45). Copyright 2012 American Society for Biochemistry & Molecular Biology.
