How oncogenic signalling coordinates glycolysis and anabolic biosynthesis in cancer cells remains unclear. We recently reported that the glycolytic enzyme phosphoglycerate mutase 1 (PGAM1) regulates anabolic biosynthesis by controlling intracellular levels of its substrate 3-phosphoglycerate (3-PG) and product 2-phosphoglycerate (2-PG). Here we report a novel mechanism in which Y26 phosphorylation enhances PGAM1 activation through release of inhibitory E19 that blocks the active site, stabilising cofactor 2,3-bisphosphoglycerate binding and H11 phosphorylation. We also report the crystal structure of H11-phosphorylated PGAM1 and find that phospho-H11 activates PGAM1 at least in part by promoting substrate 3-PG binding. Moreover, Y26-phosphorylation of PGAM1 is common in human cancer cells and contributes to regulation of 3-PG and 2-PG levels, promoting cancer cell proliferation and tumour growth. Since PGAM1 as a negative transcription target of TP53 is commonly upregulated in human cancers, these findings suggest that Y26 phosphorylation represents an additional acute mechanism underlying PGAM1 upregulation.
