ABSTRACT
The role of glutathione (GSH) and its homeodynamics during respiratory oscillation of Saccharomyces cerevisiae were investigated. Pulse injection of thiol redox modifying agents, such as diethylmaleate, N-ethylmaleimide, DL-butione-[S,R]-sulfoxamine, or 5-nitro-2-furaldehyde into the culture perturbed oscillation, although the degree of perturbation varied. Analysis of the expression profiles of GSH1 and GLR1, the activities of glutathione reductase, oscillations in cysteine and GSH concentrations, and the chemostat culture of the GLR1 disruptant indicated that GLR1 plays an essential role in the homeodynamics of GSH and the regulation of H(2)S production.
