Abstract

Letting Pyruvate In: Transport of pyruvate is an important event in metabolism whereby the pyruvate formed in glycolysis is transported into mitochondria to feed into the tricarboxylic acid cycle (see the Perspective by Murphy and Divakaruni ). Two groups have now identified proteins that are components of the mitochondrial pyruvate transporter. Bricker et al. (p. 96 , published online 24 May) found that the proteins mitochondrial pyruvate carrier 1 and 2 (MPC1 and MPC2) are required for full pyruvate transport in yeast and Drosophila cells and that humans with mutations in MPC1 have metabolic defects consistent with loss of the transporter. Herzig et al. (p. 93 , published online 24 May) identified the same proteins as components of the carrier in yeast. Furthermore, expression of the mouse proteins in bacteria conferred increased transport of pyruvate into bacterial cells.

  • Pyruvate is imported into mitochondria through the mitochondrial pyruvate carrier (MPC).

    “Pyruvate, the end product of glycolysis, is imported into mitochondria through the mitochondrial pyruvate carrier (MPC) (Bricker et al., 2012; Herzig et al., 2012).”
  • In normoxia, pyruvate is generated via glycolysis and transported across the IMM through the Mitochondrial Pyruvate Carrier, then catabolized inside mitochondria through the TCA cycle.

    “In normoxia, pyruvate is generated via glycolysis and transported across the IMM through the Mitochondrial Pyruvate Carrier (MPC).15,16 Pyruvate is further catabolized inside mitochondria through the TCA cycle.”
  • Pharmacological inhibition of MPC represses mitochondrial pyruvate uptake, shifting reliance to glycolysis for ATP production.

    “Pharmacological inhibition of MPC represses mitochondrial pyruvate uptake, shifting reliance to glycolysis for ATP production.”
  • The genes MPC1 and MPC2 encode the multimeric mitochondrial pyruvate carrier (MPC) complex embedded in the mitochondrial inner membrane.

    “Two recent studies revealed strong evidence that the genes, renamed MPC1 and MPC2, encode the multimeric mitochondrial pyruvate carrier (MPC) complex embedded in the mitochondrial inner mitochondrial membrane (Bricker et al., 2012; Herzig et al., 2012).”

  • These results are consistent with the severe growth defect previously observed in yeast with deletions in both mpc1 and mitochondrial malic enzyme growing on glucose.

    “These results are consistent with the severe growth defect previously observed in yeast with deletions in both mpc1 and mitochondrial malic enzyme growing on glucose (Bricker et al., 2012), highlighting the remarkably conserved nature of metabolism across species.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
