Pyrroloquinoline quinone (PQQ) is the organic cofactor in soybean lipoxygenase‐1 [PDF]
Treatment of soybean lipoxygenase‐1 (SLO) with phenylhydrazine (PH) induced inactivation and a maximum (350 nm) in the absorption spectrum of the enzyme. To detach the product having this absorption maximum, proteolysis was required. The product appeared to be the C(5) phenylhydrazone of pyrroloquinoline quinone (PQQ).

DETECTION METHOD OF PYRROLOQUINOLINE QUINONE (PQQ) AND PQQ-ADDUCTS BY ISOTACHOPHORESIS
New detection method of pyrroloquinoline quinone (PQQ) and PQQ-adducts has been developed by isotachophoresis using a UV and a potential gradient detectors. The detection limits of free PQQ and PQQ-acetone adduct were about 0.1μM in the sample injection of 10μl.
