Unique regulation of glyoxalase I activity during osmotic stress response in the fission yeast Schizosaccharomyces pombe: neither the mRNA nor the protein level of glyoxalase I increase under conditions that enhance its activity.

Abstract excerpt

Glyoxalase I is a ubiquitous enzyme that catalyzes the conversion of methylglyoxal, a toxic 2-oxoaldehyde derived from glycolysis, to S-D-lactoylglutathione. The activity of glyoxalase I in the fission yeast Schizosaccharomyces pombe was increased by osmotic stress induced by sorbitol. However, neither the mRNA levels of its structural gene nor its protein levels increased under the same conditions. Cycloheximide...
