RAS2/PKA pathway activity is involved in the nitrogen regulation of L-leucine uptake in Saccharomyces cerevisiae.

Abstract

The aim of the present work is to study the participation of RAS2/PKA signal pathway in the nitrogen regulation of L-leucine transport in yeast cells. The study was performed on Saccharomyces cerevisiae isogenic strains with the normal RAS2 gene, the RAS2val19 mutant and the disrupted ras2::LEU2. These strains bring about different activities of the RAS2… (More)
