Protein CoAlation: a redox-linked post-translational modification
Abstract
Regulation of metabolic pathways by signal transduction and transcriptional cascades can alter cellular levels of metabolites. Metabolites themselves can also have regulatory activity as shown in a new study published in the Tsuchiya et al. describe a novel antibody and mass spectrometry-based method for identifying proteins that are reversibly modified with Coenzyme A (CoA). Analysis of the 'CoAlated proteome' under conditions of oxidative and metabolic stress revealed a bias towards the modification of metabolic enzymes by CoA. Furthermore, CoAlation was shown to alter the activity of target proteins. These results suggest that CoAlation is a widespread post-translational modification that may have important roles in the metabolic response to stress.
