| + | To justify the localization ability of fusion membrane proteins mentioned above, we constructed a novel fusion protein called '''BlaLG'''. β-lactamase is fused to the N-terminus of Lgt and GFP is fused to the C-terminus of Lgt. The fusion protein in under control of araBAD promoter . | ||

| + | To prove whether our membrane protein equipped with those interacting protein could assemble with each other, we conducted fluorescence complementation assay. | ||
| + | In fluorescence complementation assay, proteins that are postulated to interact are fused to unfolded complementary fragments of EGFP and expressed in E.coli. Interaction of these proteins will bring the fluorescent fragments within proximity, allowing the reporter protein to reform in its native three-dimensional structure and emit its fluorescent signal. | ||
| + | EGFP was split into two halves, named 1EGFP and 2EGFP respectively. If there is interaction between two proteins which were fused with 1EGFP and 2EGFP, it is expected that fluorescence should be observed. Otherwise, no fluorescence could be observed. | ||

Proteins within each group were expressed in ''E.coli''. If there exists interaction within membrane proteins of each group, we expected to observe fluorescence on ''E.coli'' membrane. Control group is supposed to show much weaker fluorescence]] | ||
