CC -!- FUNCTION: Flavin transferase that catalyzes the transfer of the FMN
CC moiety of FAD and its covalent binding to the hydroxyl group of a
CC threonine residue in a target flavoprotein such as NqrB and NqrC, two
CC subunits of the NQR complex. {ECO:0000250|UniProtKB:A5F5Y3}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=FAD + L-threonyl-[protein] = AMP + FMN-L-threonyl-[protein] +
CC H(+); Xref=Rhea:RHEA:36847, Rhea:RHEA-COMP:11060, Rhea:RHEA-
CC COMP:11061, ChEBI:CHEBI:15378, ChEBI:CHEBI:30013, ChEBI:CHEBI:57692,
CC ChEBI:CHEBI:74257, ChEBI:CHEBI:456215; EC=2.7.1.180;
CC Evidence={ECO:0000250|UniProtKB:A5F5Y3};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:A5F5Y3};
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000250|UniProtKB:P41780, ECO:0000255|PROSITE-ProRule:PRU00303};
CC Lipid-anchor {ECO:0000250|UniProtKB:P41780, ECO:0000255|PROSITE-
CC ProRule:PRU00303}; Periplasmic side {ECO:0000250|UniProtKB:P41780}.
CC -!- SIMILARITY: Belongs to the ApbE family. {ECO:0000305}.
