Abstract

Since the pioneering work of Rapkine (1931) the hypothesis that many rhythmic life processes may involve cyclic interconversion of dithiols to disulphides provides a central theme that unifies ultradian, cell division cycle and circadian rhythm research. We have shown that in an autonomously-oscillating continuous culture of Saccharomyces cerevisiae ultradian (τ = 40 min) cycles between high and low respiratory states are accompanied by redox cycling of nicotinamide nucleotide(s) and glutathione. This system may provide insights into regulation of rhythmic processes with longer periods.
