CC -!- FUNCTION: Catalyzes the cross-linking of a glutamate residue and a
CC tyrosine residue in the PqqA protein as part of the biosynthesis of
CC pyrroloquinoline quinone (PQQ). {ECO:0000255|HAMAP-Rule:MF_00660}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[PQQ precursor protein] + S-adenosyl-L-methionine = 5'-
CC deoxyadenosine + E-Y cross-linked-[PQQ precursor protein] + H(+) + L-
CC methionine; Xref=Rhea:RHEA:56836, Rhea:RHEA-COMP:14800, Rhea:RHEA-
CC COMP:14801, ChEBI:CHEBI:15378, ChEBI:CHEBI:17319, ChEBI:CHEBI:57844,
CC ChEBI:CHEBI:59789, ChEBI:CHEBI:141026, ChEBI:CHEBI:141027;
CC EC=1.21.98.4; Evidence={ECO:0000255|HAMAP-Rule:MF_00660};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00660};
CC Note=Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3
CC cysteines and an exchangeable S-adenosyl-L-methionine.
CC {ECO:0000255|HAMAP-Rule:MF_00660};
CC -!- PATHWAY: Cofactor biosynthesis; pyrroloquinoline quinone biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_00660}.
CC -!- SUBUNIT: Interacts with PqqD. The interaction is necessary for activity
CC of PqqE. {ECO:0000255|HAMAP-Rule:MF_00660}.
CC -!- SIMILARITY: Belongs to the radical SAM superfamily. PqqE family.
CC {ECO:0000255|HAMAP-Rule:MF_00660}.
