ID:SRR_HUMAN DESCRIPTION: RecName: Full=Serine racemase; EC=4.3.1.17; EC=4.3.1.18; EC=5.1.1.18; AltName: Full=D-serine ammonia-lyase; AltName: Full=D-serine dehydratase; AltName: Full=L-serine ammonia-lyase; AltName: Full=L-serine dehydratase; FUNCTION: Catalyzes the synthesis of D-serine from L-serine. D- serine is a key coagonist with glutamate at NMDA receptors. Has dehydratase activity towards both L-serine and D-serine. CATALYTIC ACTIVITY: L-serine = D-serine. CATALYTIC ACTIVITY: L-serine = pyruvate + NH(3). CATALYTIC ACTIVITY: D-serine = pyruvate + NH(3). COFACTOR: Pyridoxal phosphate. ENZYME REGULATION: Allosterically activated by magnesium, and possibly also other divalent metal cations. Allosterically activated by ATP, ADP or GTP. Competitively inhibited by malonate. BIOPHYSICOCHEMICAL PROPERTIES: Kinetic parameters: KM=6.5 mM for L-serine; SUBUNIT: Homodimer. TISSUE SPECIFICITY: Brain: expressed at high levels in hippocampus and corpus callosum, intermediate levels in substantia nigra and caudate, and low levels in amygdala, thalamus, and subthalamic nuclei. Expressed in heart, skeletal muscle, kidney and liver. PTM: S-nitrosylated, leading to decrease the enzyme activity (By similarity). SIMILARITY: Belongs to the serine/threonine dehydratase family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
