An improved enzymatic method for the determination of pyrroloquinoline quinone, a novel prosthetic group of some important oxidoreductases, has been developed with cytoplasmic membrane of Escherichia coli K-12, in which D-glucose dehydrogenase (EC 1.1.99.17) was completely resolved to apo-enzyme by EDTA treatment. Incubation of the EDTA-treated membrane with exogenous pyrroloquinoline quinone in the presence of magnesium ions gave a quantitative determination of pyrroloquinoline quinone by assaying the restored D-glucose dehydrogenase activity. This novel enzymatic method was confirmed to be highly reproducible up to 10 ng of pyrroloquinoline quinone and could be applied to a routine assay of pyrroloquinoline quinone.
