The 3D structure of the complex between RO and its substrate reticuline show the cofactor FAD having bicovalent attachment to RO His and Cys. The substrate reticuline is seen in the active site cavity interacting with FAD and numerous RO sidechains<ref>PMID:18953357</ref>.

Two different <scene name='87/873795/Cv/6'>helix-helix interactions between Rab and SNAP-25</scene> are seen. One involves 2 monomers of SNAP-25 and the other involves one monomer<ref>PMID:28634303</ref>. Rab chain A interacts only with SNAP-25 chain D, while Rab chain B interacts with 2 SNAP-25 chains D (residues that interact with Rab chain B are colored salmon) and F.
