Physiological control of metabolic flux: the requirement for multisite modulation

Open access
Fell, D A, Thomas, S·1995·Biochemical Journal

Abstract

Biochemists have long assumed that the flux through a metabolic pathway can be controlled by the activity of a key regulatory enzyme near the beginning of the pathway. We present the accumulating evidence that every step in this assumption is flawed. Instead, effective physiological control of metabolism is shown to involve simultaneous multisite modulation through action on a number of enzymes.

  • Mammalian cells' glycolytic flux can be genetically altered with surprising ease, at least in MEFs.

    “Although it has been suggested that the activity of complex metabolic pathways cannot be modulated by the abundance of a single component enzyme (49), our studies reveal the unexpected ease with which the glycolytic flux of mammalian cells can be genetically manipulated, at least in MEFs.”

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.
