The study demonstrates that cells can manage potentially toxic levels of cysteine by converting it to non-reactive thiol forms and utilizing the metabolic products for cell growth.
The frequency of yeast [PSI+] prion formation is increased during chronological ageing
Shaun H. Speldewinde and Chris M.
