背景资料

Protocatechuate dioxygenase (PCD) catalyzes the proximal extradiol ring cleavage of protocatechuate (PCA) with attendant incorporation of both atoms of oxygen from O2.{15534} The PCD holoenzyme consists of α (23 kDa) and β (26.5 kDa) subunits, which form a tetramer with four ferric ions for a total weight of ~200 kDa.{15536} Iron is essential for activity because the substrate, PCA, initially binds directly to the iron through both hydroxyl groups to form a chelate complex.{15534} PCD is an important component of bacterial metabolism of aromatic compounds found in the soil. However, many publications are now reporting the usefulness of the PCD/PCA oxygen scrubbing (oxygen scavenging) system for maintaining anaerobic experimental conditions.{15535,15565} Cayman’s protocatechuate dioxygenase is the 3,4-PCD expressed and purified from a bacterial overexpression system. 3,4-PCD catalyzes the oxidative ring cleavage of 3,4-dihydroxybenzoate to produce β-carboxy-cis,cis-muconate. Activity of the PCD can be measured by monitoring the rate of O2 uptake with an oxygen electrode, or by measuring the amount of product (β-carboxy-cis,cis-muconate) formed at 290 nm.
