High resolution 31P nuclear magnetic resonance studies of intact yeast cells.
Open accessAbstract
High resolution 31P nuclear magnetic resonance (NMR) spectra at 145.7 MHZ are presented for intact yeast cells. Several peaks are resolved and assigned. They include the middle phosphate peaks from long chain or cyclic polyphosphates. Our results are consistent with the suggestion that these polyphosphates act as a phosphate store in the cell. We have also been able to measure cytoplasmic pH using the orthophosphate peak inside the cell, as compared with outside the cell. The results show that yeast cells maintain their cytoplasmic pH around 6.3. This value is considerably higher than the acidic extracellular pH at which they normally live. These preliminary results indicate that 31P NMR at 145.7 MHZ can be a rapid, informative, and non-invasive method for probing biochemical events within living cells.

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.
