In vitro studies on pathways and regulation of electron transport to nitrogenase with a cell-free extract from heterocysts of Anabaena variabilis


A cell-free preparation of heterocysts from Anabaena variabilis showed high nitrogenase activities with several physiological electron donors, dependent on addition of an ATP-generating system. Light-induced acetylene reduction with the artificial electron donor to photosystem I, diaminodurol, exhibited the same light saturation as with hydrogen as donor… (More)
