Abstract
The glutamate and glutamine pool contains abut 75% of the free amino acids of Anacystis nidulans harvested from a growing culture. Light pulses induced oscillations of the rate of oxygen uptake and of the size of the glutamate pool under certain physiological conditions. The frequencies of these oscillations were similar. During the oscillation the size of the glutamate pool was transiently reduced to about 50% of the dark level. The pool size of 2-oxoglutarate did not show similar oscillations. A phase plane plot of the glutamate against the respiration oscillation supported a connection of both oscillatons.Keywords
