Study Title1H NMR metabolomics corroborates serine hydroxymethyltransferase as the primary target of 2-aminoacrylate in a ridA mutant of Salmonella enterica
Study TypeNMR metabolomics on Salmonella enterica
Study SummaryThe reactive intermediate deaminase RidA (EC: is conserved across all domains of life and deaminates reactive enamine species. When S. enterica ridA mutants are grown in minimal medium, 2-aminoacrylate (2AA) accumulates, damages several pyridoxal 5’-phosphate (PLP)- dependent enzymes, and elicits an observable growth defect. Genetic studies suggested that damage to serine hydroxymethyltransferase (GlyA), and the resultant depletion of 5,10-methelenetetrahydrofolate (5,10-mTHF), was responsible for the observed growth defect. However, the downstream metabolic consequence from GlyA damage by 2AA remains relatively unexplored. This study sought to use untargeted 1H NMR metabolomics to determine whether the metabolic state of a S. enterica ridA mutant was accurately reflected by characterizing growth phenotypes. The data supported the conclusion that metabolic changes in a ridA mutant were due to the IlvA-dependent generation of 2AA, and that the majority of these changes were a consequence of damage to GlyA. While many of the shifts in the metabolome of a ridA mutant could be explained, changes in some metabolites were not easily modeled, suggesting that additional levels of metabolic complexity remain to be unraveled.
