Transcriptional regulation of the MET3 gene of Saccharomyces cerevisiae.

Abstract

The MET3 gene, coding for ATP sulfurylase (ATPS), an enzyme implicated in methionine biosynthesis in Saccharomyces cerevisiae, was cloned by functional complementation, after transformation, of a yeast met3 mutant strain. The cloned MET3 gene was used as a probe to measure the specific MET3 messenger RNA in a wild-type strain grown under conditions which promote or fail to promote repression of ATPS synthesis. It was found that the level of MET3 messenger RNA is reduced ten-fold when the strain is grown under conditions where ATPS synthesis is repressed, suggesting that the MET3 expression is regulated transcriptionally. The direction of transcription and the size of the transcript have been determined.
