Enzyme Information

2.7.1.180

FAD:protein FMN transferase.

based on mapping to UniProt P0AB85

FAD + [protein]-L-threonine = [protein]-FMN-L-threonine + AMP.

-!- The enzyme catalyzes the transfer of the FMN portion of FAD and its covalent binding to the hydroxyl group of an L-threonine residue in a target flavin-binding protein such as the B and C subunits of EC 7.2.1.1.
