Metabolomics analysis of an AAA-ATPase Cdc48-deficient yeast strain.

ABSTRACT: The ubiquitin-specific chaperone AAA-ATPase Cdc48 and its orthologs p97/valosin-containing protein (VCP) in mammals play crucial roles in regulating numerous intracellular pathways via segregase activity, which separates polyubiquitinated targets from membranes or binding partners. Interestingly, high-throughput experiments show that a vast number of metabolic enzymes are modified with ubiquitin. Therefore, Cdc48 may regulate metabolic pathways, for example by acting on the polyubiquitin chains of metabolic enzymes; however, the role of Cdc48 in metabolic regulation remains largely unknown. To begin to analyze the role of Cdc48 in metabolic regulation in yeast, we performed a metabolomics analysis of temperature-sensitive cdc48-3 mutant cells. We found that the amount of metabolites
