Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

GABA shunt mediates thermotolerance in Saccharomyces cerevisiae by reducing reactive oxygen production.

Cao J, Barbosa JM, Singh NK, Locy RD

The GABA shunt pathway involves three enzymes: glutamate decarboxylase (GAD), GABA aminotransferase (GAT), and succinate semialdehyde dehydrogenase (SSADH). These enzymes act in concert to convert glutamate (α-ketoglutarate) to succinate. Deletion mutations in each of these genes in Saccharomyces cerevisiae resulted in growth defects at 45°C. Double and triple mutation constructs were compared for thermotolerance with the wild type and single ... [more]
