Abstract

High levels of d -serine occur in mammalian brain, where it appears to be an endogenous ligand of the glycine site of N -methyl- d -aspartate receptors. In glial cultures of rat cerebral cortex, d -serine is enriched in type II astrocytes and is released upon stimulation with agonists of non- N -methyl- d -aspartate glutamate receptors. The high levels of d -serine in discrete areas of rat brain imply the existence of a biosynthetic pathway. We have purified from rat brain a soluble enzyme that catalyzes the direct racemization of l -serine to d -serine. Purified serine racemase has a molecular mass of 37 kDa and requires pyridoxal 5′-phosphate for its activity. The enzyme is highly selective toward l -serine, failing to racemize any other amino acid tested. Properties such as pH optimum, K m values, and the requirement for pyridoxal phosphate resemble those of bacterial racemases, suggesting that the biosynthetic pathway for d -amino acids is conserved from bacteria to mammalian brain.

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.
