| PP_0375 | pqqD-I | PP_0375 | PP_0377 | Prolyl oligopeptidase family protein. | Coenzyme PQQ synthesis protein D; Functions as a PqqA binding protein and presents PqqA to PqqE, in the pyrroloquinoline quinone (PQQ) biosynthetic pathway. | 0.887 |
| PP_0375 | pqqE | PP_0375 | PP_0376 | Prolyl oligopeptidase family protein. | Coenzyme PQQ synthesis protein E; Catalyzes the cross-linking of a glutamate residue and a tyrosine residue in the PqqA protein as part of the biosynthesis of pyrroloquinoline quinone (PQQ). | 0.926 |
