CC -!- FUNCTION: Catalyzes the complex heterocyclic radical-mediated
CC conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7-
CC deazaguanine (CDG), a step common to the biosynthetic pathways of all
CC 7-deazapurine-containing compounds. {ECO:0000255|HAMAP-Rule:MF_00917}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=6-carboxy-5,6,7,8-tetrahydropterin + H(+) = 7-carboxy-7-
CC deazaguanine + NH4(+); Xref=Rhea:RHEA:27974, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:28938, ChEBI:CHEBI:61032, ChEBI:CHEBI:61036; EC=4.3.99.3;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00917};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00917};
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_00917};
CC -!- COFACTOR:
CC Name=S-adenosyl-L-methionine; Xref=ChEBI:CHEBI:59789;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00917};
CC Note=Binds 1 S-adenosyl-L-methionine per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00917};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00917};
CC -!- PATHWAY: Purine metabolism; 7-cyano-7-deazaguanine biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_00917}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00917}.
CC -!- SIMILARITY: Belongs to the radical SAM superfamily. 7-carboxy-7-
CC deazaguanine synthase family. {ECO:0000255|HAMAP-Rule:MF_00917}.
