Cloning of the ASN1 and ASN2 genes encoding asparagine synthetases in Saccharomyces cerevisiae: differential regulation by the CCAAT‐box‐binding factor

Abstract
Two new yeast genes, named ASN1 and ASN2, were isolated by complementation of the growth defect of an asparagine auxotrophic mutant. Genetical analysis indicates that these two genes are allelic to ...
