Structure of the pyrroloquinoline quinone radical in quinoprotein ethanol dehydrogenase.

Quinoprotein alcohol dehydrogenases use the pyrroloquinoline quinone (PQQ) cofactor to catalyze the oxidation of alcohols. The catalytic cycle is thought to involve a hydride transfer from the alcohol to the oxidized PQQ, resulting in the generation of aldehyde and reduced PQQ. Reoxidation of the cofactor by cytochrome proceeds in two sequential steps via the PQQ radical. We have used a combina...

Quinoprotein alcohol dehydrogenase from ethanol-grown Pseudomonas aeruginosa.

Cell-free extracts of Pseudomonas aeruginosa strains, grown on ethanol, showed dye-linked alcohol dehydrogenase activities. The enzyme responsible for this activity was purified to homogeneity. It appeared to contain two molecules of pyrroloquinoline quinone per enzyme molecule. In many respects, it resembled other quinoprotein alcohol dehydrogenases (EC 1.1.99.8), having a substrate specificit...

Substrate binding in quinoprotein ethanol dehydrogenase from Pseudomonas aeruginosa studied by electron-nuclear double resonance.

Binding of methanol to the quinoprotein ethanol dehydrogenase from Pseudomonas aeruginosa has been studied by pulsed electron-nuclear double resonance at 9 GHz. Shifts in the hyperfine couplings of the pyrroloquinoline quinone radical provide direct evidence for a change in the environment of the cofactor when substrate is present. By performing experiments with deuteriated methanol, we confirm...

Factors relevant in bacterial pyrroloquinoline quinone production.

Quinoprotein content and levels of external pyrroloquinoline quinone (PQQ) were determined for several bacteria under a variety of growth conditions. From these data and those from the literature, a number of factors can be indicated which are relevant for PQQ production. Synthesis of PQQ is only started if synthesis of a quinoprotein occurs, but quinoprotein synthesis does not depend on PQQ sy...

Reversible thermal inactivation of the quinoprotein glucose dehydrogenase from Acinetobacter calcoaceticus. Ca2+ ions are necessary for re-activation.

The soluble form of the homogeneous quinoprotein glucose dehydrogenase from Acinetobacter calcoaceticus is reversibly inactivated at temperatures above 35 degrees C. An equilibrium is established between active and denatured enzyme, this depending on the protein concentration and the inactivation temperature used. Upon thermal inactivation the enzyme dissociates into the prosthetic group pyrrol...

Quaternary structure of quinoprotein ethanol dehydrogenase from Pseudomonas aeruginosa and its reoxidation with a novel cytochrome c from this organism.

Quinoprotein (2,7,9-tricarboxy-1H-pyrrolo-[2,3-f]quinoline-4,5-dione quinone form (PQQ)-containing) ethanol dehydrogenase (EDH) from Pseudomonas aeruginosa ATCC 17933 was purified to homogeneity. EDH has an alpha 2 beta 2 configuration and subunits comparable in size to those of methanol dehydrogenase (MDH). Compared with other PQQ-containing dehydrogenases, Ca2+ is rather loosely bound and it ...
