The important requirements for these are the efficient production, purification and correctly folded forms of these proteins. We report here the cloning, easy expression and characterization of a sunflower multicystatin (SMC) as a functional fusion protein in <i>E. coli</i>. For the first time, the amplified cystatin coding region was expressed as a part of maltose-binding fusion protein using pMALc2X over-expression vector in TB1 strain of <i>E. coli </i>without<i> </i>affecting the recombinant bacterial growth. In comparison to the previously prepared recombinant SMC (rSMC), a high amount (~44 mg/L of bacterial cell culture) of purified fused SMC (fSMC) was obtained using single-step purification method. fSMC strongly inhibited papain activity <i>in vitro</i> as compared to <i>Celosia</i> single-domain cystatin<i>. </i>Purified fSMC may be used for basic biochemical, pharmacological or clinical studies without the cleavage of its fusion parts.</span> |
