Serine racemase and the serine shuttle between neurons and astrocytes

Biochimica Et Biophysica Acta - Proteins and Proteomics, 2011
d-Serine is a brain-enriched d-amino acid that works as a transmitter-like molecule by physiologically activating NMDA receptors. Synthesis of d-serine is carried out by serine racemase (SR), a pyridoxal 5'-phosphate-dependent enzyme. In addition to carry out racemization, SR α,β-eliminates water from l- or d-serine, generating pyruvate and NH(4 ...

Reactions of Serine Palmitoyltransferase with Serine and Molecular Mechanisms of the Actions of Serine Derivatives as Inhibitors

Biochemistry, 2004
Serine palmitoyltransferase (SPT) is a key enzyme in sphingolipid biosynthesis and catalyzes the decarboxylative condensation of L-serine and palmitoyl coenzyme A to 3-ketodihydrosphingosine. We have succeeded in the overproduction of a water-soluble homodimeric SPT from Sphingomonas paucimobilis EY2395(T) in Escherichia coli.

Mechanism of eukaryotic serine racemase-catalyzed serine dehydration

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2020
Eukaryotic serine racemase (SR) is a pyridoxal 5'-phosphate enzyme belonging to the Fold-type II group, which catalyzes serine racemization and is responsible for the synthesis of D-Ser, a co-agonist of the N-methyl-d-aspartate receptor. In addition to racemization, SR catalyzes the dehydration of D- and L-Ser to pyruvate and ammonia.

KAHA Ligation at Serine

ChemBioChem, 2015
Oxazetidine assisted KAHA ligation was developed by the Bode group as an efficient peptide segment ligation strategy at native serine residues. This milestone achievement should enable the chemical synthesis of difficult-to-prepare proteins for biological studies.

D-Serine

Current Opinion in Clinical Nutrition and Metabolic Care, 2013
Here, we discuss the recent data on the role of different N-methyl D-aspartate receptor (NMDAR) coagonists, D-serine and glycine, in regulating NMDAR activity and neurotoxicity.D-Serine originates from both neurons and astrocytes, from where it is released by different mechanisms.
