General Information

General Information Comment Organism
evolution sequence polymorphisms among the alpha-glucosidase family lead to interesting variability of gene expression patterns and of catalytic efficiencies on different substrates, which altogether account for the absence of functional redundancy for growth on isomaltose Saccharomyces cerevisiae
metabolism expression of the IMAx genes is regulated by carbon sources, putative binding sites of transcriptional regulators, overview. Ima1p isomaltase and Agt1p transporter are essential for isomaltose assimilation Saccharomyces cerevisiae
