Randomized trial demonstrates metabolic enzyme regulation in response to carbon sources, indicating metabolic flexibility.

The study aims to understand how lysine acetylation affects metabolic processes in prokaryotes, specifically in Salmonella.
Analyzed effects of different carbon sources on lysine acetylation of metabolic enzymes in Salmonella.
Investigated enzyme activities involved in glycolysis, gluconeogenesis, citrate cycle, and glyoxylate bypass.
Monitored expression of lysine acetyltransferase and deacetylase correlated with growth status.
Lysine acetylation of central metabolic enzymes varied significantly based on carbon sources, affecting cell growth.
Key enzymes regulating glycolysis and gluconeogenesis showed altered activities due to acetylation changes.
Acetyltransferase and deacetylase expression responded dynamically to energy status, facilitating metabolic adaptation.

Wang et al. (2010) studied this question.
