Function

function

Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7-deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.

Catalytic activity

Cofactor

Protein has several cofactor binding sites:
Mg2+ (UniProtKB | Rhea| CHEBI:18420 )

S-adenosyl-L-methionine (UniProtKB | Rhea| CHEBI:59789 )

Note: Binds 1 S-adenosyl-L-methionine per subunit.
[4Fe-4S] cluster (UniProtKB | Rhea| CHEBI:49883 )

Note: Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.

Pathway

Purine metabolism; 7-cyano-7-deazaguanine biosynthesis.
