While it is increasingly recognised that signalling and metabolism are highly interconnected, the underpinning mechanisms of their co-regulation are still largely unknown. Here we designed and acquired proteomics, phosphoproteomics, and metabolomics experiments in fumarate hydratase (FH) deficient cells and developed a computational modelling approach to identify putative regulatory phosphorylation-sites of metabolic enzymes. We identified previously reported functionally relevant phosphosites and potentially novel regulatory residues in enzymes of the central carbon metabolism. In particular, we show that pyruvate dehydrogenase (PDHA1) enzymatic activity is inhibited by increased phosphorylation in FH-deficient cells. Our work provides a novel approach to investigate how post-translational modifications of enzymes regulate metabolism and could have important implications for understanding the metabolic transformation of FH-deficient cancers.<\/jats:p>","DOI":"10.1101\/149716","type":"posted-content","created":{"date-parts":[[2017,6,14]],"date-time":"2017-06-14T01:10:17Z","timestamp":1497402617000},"source":"Crossref","is-referenced-by-count":0,"title":["Post-translational regulation of metabolism in fumarate hydratase deficient cancer cells"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9967-5205","authenticated-orcid":false,"given":"Emanuel","family":"Gon\u00e7alves","sequence":"first","affiliation":[]},{"given":"Marco","family":"Sciacovelli","sequence":"additional","affiliation":[]},{"given":"Ana S.
