although the purified oxidase showed a substrate specificity similar to that of pqq-dependent pva dehydrogenase and about threefold-higher pva-dehydrogenating activity with phenazine methosulfate or phenazine ethosulfate than pva oxidase activity with h2o2 formation , it was shown that the enzyme does not contain pqq as the coenzyme , and pqq did not affect its activity .
