Cloning and characterization of the iron-sulfur subunit gene of succinate dehydrogenase from Saccharomyces cerevisiae

Abstract

We describe the cloning and characterization of the complete gene for the iron-sulfur protein subunit of succinate dehydrogenase (EC 1.3.99.1) from Saccharomyces cerevisiae. The promoter and coding sequence have been cloned into an Escherichia coli-yeast shuttle vector. The cloned gene complements the defect in a succinate dehydrogenase-deficient yeast mutant isolated by us, and gene expression is fully responsive to induction by glucose deprivation, indicating that the promoter is intact.
