A glutathione S-transferase (GST) gene has been cloned from Schizosaccharomyces pombe for the first time. The nucleotide sequence determined was found to contain 2030 base pairs including an open reading frame of 229 amino acids that would encode a protein of a molecular mass of 27 017 Da. The cloned GST gene was expressed and was found to function in S. pombe, Saccharomyces cerevisiae, and Escherichia coli. The plasmid pGT207 encoding the S. pombe GST gene appeared to be able to accelerate the growth of a wild type S. pombe culture. In a culture of S. pombe containing plasmid pGT207, the growth was inhibited less by mercuric chloride than in a culture with vector alone. The 1088 bp region upstream from the GST gene as well as the region encoding the N-terminal 14 amino acids was transferred into the promoterless β-galactosidase gene of plasmid YEp357R to yield the fusion plasmid pYSH2000. β-Galactosidase synthesis was induced by cadmium chloride, mercuric chloride, hydrogen peroxide, and menadione. It was also induced by high temperature. These results suggest that the cloned S. pombe GST gene is involved in the oxidative stress response.
