FUNCTION: Ring cyclization and eight-electron oxidation of 3a-(2-amino-2-carboxyethyl)-4,5-dioxo-4,5,6,7,8,9-hexahydroquinoline-7,9-dicarboxylic-acid to PQQ (By similarity).

CATALYTIC ACTIVITY: 6-(2-amino-2-carboxyethyl)-7,8-dioxo-1,2,3,4,7,8-hexahydroquinoline-2,4-dicarboxylate + 3 O(2) = 4,5-dioxo-4,5-dihydro-1H-pyrrolo[2,3-f]quinoline-2,7,9-tricarboxylate + 2 H(2)O(2) + 2 H(2)O.

PATHWAY: Cofactor biosynthesis; pyrroloquinoline quinone biosynthesis.

SIMILARITY: Belongs to the pqqC family.
