Genetic properties and chromatin structure of the yeast gal regulatory element: an enhancer-like sequence.

Abstract

DNA molecules created by fusing a 365-base-pair segment of yeast DNA encoding the galactose-regulated upstream promoter element (gal) to a set of derivatives that systematically delete sequences upstream from the his3 gene are introduced in single copy back into the yeast genome precisely at the his3 locus and then assayed for transcription. Fusions of the gal regulatory element to his3 derivatives containing all normal mRNA coding sequences but lacking essentially the entire promoter region fail to express his3 under any growth conditions. Fusions to derivatives lacking the his3 upstream promoter element but containing the "TATA box" place his3 expression under gal control--i.e., extremely high RNA levels in galactose-containing medium and essentially no his3 RNA in glucose-containing medium. However, of the two normal his3 initiation sites, only the downstream one is activated by the gal element. In fusions of this type, neither the orientation of the gal element nor the distance between the element and the his3 TATA box affects the level or the initiation points of transcription. However, the gal element does not influence transcription when placed 100 or 300 base pairs downstream from the normal mRNA start sites. Fusions to derivatives containing the entire his3 promoter region restore the basal level of his3 transcription in glucose-grown cells, and both transcriptional initiation sites are used. Furthermore, RNA levels in galactose-grown cells, although somewhat higher than in glucose-grown cells, are significantly below the fully induced level. The distance from his3 coding sequences does not affect RNA levels, suggesting that specific sequences, possibly corresponding to the his3 upstream promoter element, reduce the ability of the gal element to activate transcription. Analysis of chromatin from some of these strains indicates a DNase I-hypersensitive site(s) in the middle of the gal element. However, this structural feature is not correlated with transcriptional initiation because it is found when cells are grown in glucose medium and also in derivatives lacking a TATA box. Thus, the gal upstream element possesses most, but not all, of the properties of viral and cellular enhancer sequences of higher eukaryotes. In addition, it appears that the his3 and gal upstream sequences represent two distinct classes of promoter elements, which activate transcription from different initiation sites.
