WebThe histidine-specific permease gene (HIP1) of Saccharomyces cerevisiae has been mapped, cloned, and sequenced. The HIP1 gene maps to the right arm of chromosome VII, approx. 11 cM distal to the ADE3 gene. The gene was isolated as an 8.6-kb BamHI-Sau3A fragment by complementation of the histidine-specific permease deficiency in recipient … Webmurium histidine permease mutants were generated and ana- lyzed. Since the permease is not essential for survival, the distribution of these "natural" mutations indicates which features are essential for function. Mutants with specific properties and site-directed mutations were also generated and analyzed.
