Abstract

The manganese superoxide dismutase (MnSOD) is a mitochondrial enzyme that dismutates a potentially toxic superoxide radical into hydrogen peroxide and dioxygen. To study the regulation of the Schizosaccharomyces pombe MnSOD gene, the 943 bp upstream region was fused into the promoterless beta-galactosidase gene of the shuttle vector YEp357, which resulted in the fusion plasmid pMS14. Restriction mapping and nucleotide sequencing confirmed its construction. The synthesis of beta-galactosidase from the fusion plasmid was induced by aluminum chloride, menadione, cadmium chloride, manganese chloride, and hydrogen peroxide. It was also induced by NO-generating S-nitroso-N-acetylpenicillamine (SNAP). However, cupric chloride and zinc chloride did not affect the synthesis of beta-galactosidase from the fusion plasmid. The beta-galactosidase synthesis appeared to be independent of the Pap1 protein. These results suggest that some metals, oxidative stress, and nitric oxide regulate the S. pombe MnSOD gene.
