On initial observation, the principle behind the theory of cysteine deficiency being a cause of low glutathione appears reasonably sound, but it is not that simple
This was exemplified here by the fact that increased GSH production in the presence of 5-FOA (counter-selective for URA3 expression) appeared to be a non-specific response to 5-FOA, evident also in the control strain expressing URA3 behind pURA3 , rather than selection based on phenotypic heterogeneity as intended in this proof-of-principle study
