Abstract:
Recent evidence has failed to support the claim for a pyrroloquinoline quinone (PQQ) cofactor in mammalian enzymes previously reported to have PQQ. The validity of the original analysis now has been questioned, and a second cofactor, topa quinone, has been identified in at least one enzyme.
