Enzyme Information

1.3.3.11
Pyrroloquinoline-quinone synthase.
based on mapping to UniProt A6T9H1
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.
-!- So far only a single turnover of the enzyme has been observed, and the pyrroloquinoline quinone remains bound to it; it is not yet known what releases the product in the bacterium.
