Synonyms
Asparagine--tRNA ligase, cytoplasmic (EC:6.1.1.22), Asparaginyl-tRNA synthetase, AsnRS, Potentially protective 63 kDa antigen.
Introduction
The AsnRS enzyme is a member of the ligases family, specifically those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds. An asparagine-tRNA ligase is an enzyme which catalyzes the chemical reaction: ATP + L-asparagine + tRNAAsn AMP + diphosphate + L-asparaginyl-tRNAAsn. The three substrates of the AsnRS enzyme are ATP, L-asparagine, and tRNA(Asn), whereas its three products are AMP, diphosphate, and L-asparaginyl-tRNA(Asn).
Description
AsnRS Brugia Malayi Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 568 amino acids (including a 6xHis Tag at N-terminus) and having a molecular mass of 64.5kDa.
The AsnRS is purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile filtered colorless solution.
Formulation
AsnRS 0.2μm filtered solution containing 20mM HEPES, pH7.4, 100mM NaCl, 5mM MgCl2, 5mM b-Mercaptoethanol and 10 % Glycerol.
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.
