Abstract
The chorismate mutase structural gene, ARO7, which is necessary for both phenylalanine and tyrosine biosynthesis was cloned by complementation in yeast. Genetic analysis showed that ARO7 was identical to a gene necessary for growth in hypertonic medium, OSM2, which mapped nearby. After restriction mapping and subcloning of the plasmid, the cloned gene was used to detect mRNA levels in several growth conditions. Enzyme activities were measured in various genotypes. At our level of detection ARO7-OSM2 is a low level constitutively expressed gene.Entities:
