In mammals, biotin, well known for its role as the cofactor of carboxylases, also controls the expression not only of proteins involved in this function, but also of a large number and variety of other different proteins. As a first step towards looking for a rationale for these phenomena, we intend to compare these regulatory functions of biotin between the rat and the much less evolutionized eukaryote, Saccharomyces cerevisiae. Thus far, we have measured growth in yeast cultured on different concentrations of biotin to choose the experimental conditions to be used (2, 200 and 2000 microM) and have found that a band corresponding to the biotinylated S. cerevisiae Arc1p protein appears at streptavidin Western blots at a biotin concentration above 2000 muM, its density increasing with higher biotin amounts. We will now study changes in yeast transcriptome with these varying concentrations and compare them with changes observed in the rat.
