The pH in the cytoplasmic and thylakoid spaces of the blue-green alga, Anacystis nidulans, has been determined in the light and in the dark by uptake of 5,5-dimethyloxazolidine-2,4-dione and methylamine into the sucrose-impermeable (3)H-H(2)O space, as measured by silicon layer filtering centrifugation.Illumination causes an alkalinization in the cytoplasm(More)
Investigations of the energy-dependent accumulation of orthophosphate by the blue-green alga Anacystis nidulans have established: 1. The transport through the cell membrane is the rate-limiting step in the incorporation of phosphate.-2. This transport is facilitated by a “carrier” that can be activated by Ca2+ and Mg2+ and inhibited by EDTA.-3. The(More)
