Mussel adhesive proteins, including the 20-plus variants of foot protein type 3 (fp-3), have been suggested as potential environmentally friendly adhesives for use in aqueous conditions and in medicine. In previous study, we report the novel production of a recombinant Mytilus galloprovincialis foot protein type 3 variant A (Mgfp-3A) fused with a hexahistidine affinity ligand in Escherichia coli, and its ~99% purification with affinity chromatography. Recombinant Mgfp-3A showed a superior purification yield and better apparent solubility in 5% acetic acid (prerequisites for large-scale production and practical use) compared to those of the previously reported recombinant M. galloprovincialis foot protein type 5 (Mgfp-5). The adhesive ability of recombinant Mgfp-3A was comparable to that of Cell-Tak but lower than that of recombinant Mgfp-5. In this study, to take advantage of previously studied mussel proteins, we tried to make some kinds of hybrid derivatives from those. We made 3 kinds of recombinant vectors, expressed and purified those hybrid proteins in Escherichia coli. As a result, we can observe some changes of properties. |
