Expression of mitochondrial thioredoxin peroxidase (Prx1p) from Saccharomyces cerevisiae is subjected to complex transcriptional regulation and is responsive to the levels of several compounds such as glucose and peroxides. We have previously shown that glucose represses the expression of mitochondrial thioredoxin peroxidase gene (PRX1) in a process mediated by cAMP/protein kinase A (PKA) and Msn2/4p. Here, we show by northern blot and reporter gene (beta-galactosidase) assays that deletion of genes encoding Tor1p and Ras2p resulted in increased PRX1 expression, indicating that these proteins are also mediators of the glucose repression effect. We also identified the position of the stress transcription responsive element (STRE) in the PRX1 promoter, which is recognized by Msn2p and Msn4p activators. Mutation of AGGGG sequence at position -116 to -112 caused a high drop in PRX1 expression under respiratory conditions and in strains containing deletions of TOR1 or RAS2, confirming the finding that this sequence is a STRE.
