Chaperone Protein hchA E.Coli (Recombinant)

Synonyms

Chaperone protein hchA, EcHsp31, Hsp31, hchA, yedU, yzzC, b1967, JW1950.

Escherichia coli Hsp31 (HchA) is a homodimeric member of the ThiI/DJ-1/PfpI superfamily which combines molecular chaperone and aminopeptidase activities. HchA uses temperature-induced exposure of structured hydrophobic domains to capture and stabilize early unfolding protein intermediates under severe thermal stress.

Description

HchA produced in E. coli is a single, non-glycosylated polypeptide chain containing 303 amino acids (1-283 a.a.) and having a molecular mass of 33.3kDa. HchA is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Source

Escherichia coli

Physical Appearance

Sterile filtered colorless solution.

Formulation

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

Stability

HchA E. coli recombinant although stable at 4°C for 1 week, should be stored below -18°C. Please prevent freeze thaw cycles.
