INTRODUCTION

Serine racemase (SRR) is an enzyme which generates D-serine from L-serine. D-serine functions as a neuronal signaling molecule by activating NMDA receptors in the brain. Mammalian SRR is a pyridoxal 5'-phosphate dependent enzyme which catalyzes both the racemization of L-serine to D-serine and also the elimination of water from L-serine, producing pyruvate and ammonia. The SRR enzyme is physiologically stimulated by divalent cations (e.g., magnesium) and is allosterically activated by the magnesium/ATP complex.

DESCRIPTION

SRR Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 364 amino acids (1-340) and having a molecular mass of 39.1kDa.
SRR is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

SOURCE

Escherichia Coli.

PHYSICAL APPEARANCE

Sterile Filtered colorless solution.

FORMULATION

The SRR solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH8.0), 20% glycerol, 0.1M NaCl and 1mM DTT.

STABILITY

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. 
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
