The regulation of arginine biosynthesis in Saccharomyces cerevisiae. The specificity of argR- mutations and the general control of amino-acid biosynthesis.

The regulation of arginine biosynthetic enzymes in yeast is subjected to a double control. One level of arginine enzyme synthesis is under the control of an apo-repressor, called ARGR. ARGR molecules control specifically the arginine pathway. A second level of control of arginine biosynthesis has been disclosed. It also controls tryptophan, histidine, lysine, isoleucine-valine and probably many more biosyntheses. The general mechanism is turned on in leaky mutants in any of the amino acid pathways mentioned above.
