CC -!- FUNCTION: Radical SAM enzyme that catalyzes the addition of the
CC adenosyl radical to the double bond of 3-[(1-carboxyvinyl)oxy]benzoate,
CC leading to aminodeoxyfutalosine (AFL), a key intermediate in the
CC formation of menaquinone (MK, vitamin K2) from chorismate.
CC {ECO:0000256|HAMAP-Rule:MF_00993}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-[(1-carboxyvinyl)-oxy]benzoate + H2O + S-adenosyl-L-
CC methionine = 6-amino-6-deoxyfutalosine + H(+) + hydrogencarbonate +
CC L-methionine; Xref=Rhea:RHEA:33075, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17544, ChEBI:CHEBI:57844,
CC ChEBI:CHEBI:59789, ChEBI:CHEBI:64286, ChEBI:CHEBI:76981;
CC EC=2.5.1.120; Evidence={ECO:0000256|HAMAP-Rule:MF_00993};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00993};
CC Note=Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3
CC cysteines and an exchangeable S-adenosyl-L-methionine.
CC {ECO:0000256|HAMAP-Rule:MF_00993};
CC -!- PATHWAY: Quinol/quinone metabolism; menaquinone biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_00993}.
CC -!- SIMILARITY: Belongs to the radical SAM superfamily. MqnE family.
CC {ECO:0000256|HAMAP-Rule:MF_00993}.
