【 摘 要 】

Soybean lipoxygenase-1 was reinvestigated with respect to its quinoprotein nature. It has been reported previously that soybean lipoxygenase-1 contains pyrroloquinoline quinone as the organic cofactor [1]. Because spectroscopie data were found to be inconsistent [2] with the evidence presented in [1], we sought to reproduce the published data by carefully following the procedures described in [1] and supplementing them with new analytical results. The combined data lead us to conclude that soybean lipoxygenase-1 is not a quinoprotein.
