Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

ME2 is a mitochondrial NAD(P)+-dependent malic enzyme that catalyzes the oxidative decarboxylation of malate to pyruvate, with distinct kinetics from its paralogs (high Km for malate, dual NAD/NADP cofactor use, allosteric activation by fumarate and inhibition by ATP), and functions across multiple tissues including pancreatic islets (PMID:19691144). By generating pyruvate and reducing equivalents, ME2 sustains mitochondrial respiration, ATP production via oxidative phosphorylation, and NADPH-dependent ROS clearance, such that its loss raises oxidative stress and triggers apoptosis (PMID:37079187). ME2 activity is tuned by a convergent set of activating post-translational modifications gated by nutrient state: SIRT5-mediated desuccinylation at K346 activates ME2 under glutamine deprivation to support proliferation (PMID:38007551), ACAT1-mediated acetylation at K156 activates it under low glucose to drive pyruvate/lactate output and chemoresistance (PMID:39951294), and PRMT1-mediated methylation activates it to promote hepatocellular carcinoma growth (PMID:39528487). Phosphorylation of the full-length cytoplasmic isoform (ME2fl) at S9 by AKT1 blocks its mitochondrial import and converts it into a scaffold that assembles glycolytic enzymes (PFKL, GAPDH, PKM2, LDHA), switching metabolism toward aerobic glycolysis (PMID:38263319). ME2-derived pyruvate also stabilizes β-catenin to promote migration and invasion (PMID:37110198). A homozygous frameshift variant producing truncated, unstable ME2 protein causes a human neurodevelopmental disorder, and the growth arrest of yeast lacking the ME2 ortholog is rescued by human ME2, establishing an essential mitochondrial role (PMID:39401966). The enzyme is allosterically druggable at a site distinct from the active site (embonic acid) and by active-site-directed inhibitors (NPD389) (PMID:26008970, PMID:24681895).
