Common and divergent features of galactose-1-phosphate and fructose-1-phosphate toxicity in yeast

Mol Biol Cell. 2018 Apr 15;29(8):897-910. doi: 10.1091/mbc.E17-11-0666. Epub 2018 Mar 30.

Abstract

Metabolic dysregulation leading to sugar-phosphate accumulation is toxic in organisms ranging from bacteria to humans. By comparing two models of sugar-phosphate toxicity in Saccharomyces cerevisiae, we demonstrate that toxicity occurs, at least in part, through multiple, isomer-specific mechanisms, rather than a single general mechanism.
