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 |
