Overexpression of TrxA::BjMT2 (Thioredoxin::Metallothionein Type 2 from Brassica juncea) Fusion Protein in Escherichia coli and In Vitro Cleavage by TEV Protease

Abstract:

BjMT2 cDNA clone gene isolated from Brassica juncea was constructed in pETM-20 and expressed in E.coli as a TrxA::BjMT2 fusion protein. After affinity chromatography and cleavage from the TrxA domain, pure BjMT2 protein was obtained which strongly reacted with the thiol reagent monobromobimane. The amino acid sequence determined by mass spectrograph revealed the polypeptide contains 80 amino acids and is full of 8 and 6 cysteines with CC, CXC and C-XX-C motifs clustered near -N and -C terminus, respectively.
