Regulation of the ilv 1 multifunctional gene in Saccharomyces cerevisiae

  • Arthur P. Bollon


  1. 1.

    The ilv1 gene in S. cerevisiae codes for a regulatory protein involved in depression of the ilv 2 and ilv 3 genes as well as a biosynthetic enzyme, threonine deaminase.

  2. 2.

    The ilv 1 gene does not autogenously regulate its catalytic product threonine deaninase.

  3. 3.

    Regulation of the ilv 2 and ilv 3 gene products involve different aporepressors than regulation of the ilv 1 gene product.

  4. 4.

    The ilv 1 multifunctional gene in S. cerevisiae may be a duplication and fusion of a bacterial like ilv 1 gene where ilv 1 catalytic and regulatory functions have been differentially conserved.
