Abstract Many sets of genes in Saccharomyces cerevisiae are divergently transcribed, but at present there are no vectors generally available for the simultaneous analysis of divergent transcription from these promoters. In the present study MEL1 and lacZ were used to construct a vector capable of measuring the divergent expression initiated by the MAL6T-MAL6S bi-directional promoter. Our observations demonstrate that the expression of both reporter genes was regulated in a similar fashion to the native MAL6T and MAL6S genes, and that induction was dependent upon the presence of a functional MALR activator gene. The results confirmed that the MAL6T-MAL6S promoter was co-ordinately regulated, repressed by glucose, induced by maltose, and that basal expression was more active in the MAL6S direction than in the MAL6T direction.
