| Abstract: | Abstract Light-induced proton efflux has been investigated with intact cells of Anabaena, Nostoc, Anacystis , and Aphanocapsa . The proton efflux by filamentous blue-green algae is biphasic, strongly inhibited by ortho -vanadate and insensitive to cyanide. These data are taken as evidence for a proton-pumping ATP-hydrolase present on the cytoplasmic membrane of Anabaena and Nostoc . |
