Coenzyme PQQ synthesis protein E (IPR017200)

Short name: PqqE

Overlapping homologous superfamilies

Family relationships


This entry represents coenzyme PQQ biosynthesis protein E, which is a prototypical peptide-cyclising radical SAM enzyme. It links a Tyr to a Glu as the first step in the biosynthesis of pyrrolo-quinoline-quinone (coenzyme PQQ) from the precursor peptide PqqA. PQQ is required for some glucose dehydrogenases and alcohol dehydrogenases.
