Relevance Rab is a major auto antigen in lymphocytic infundibulo-neurohypophysitis (LINH). Antibodies to Rab may serve as a biomarker for the diagnosis of LINH. Structural highlights 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.
