A) Map of E. coli expression vector plasmid pET32 harboring eGFP-gp16 with His-tag. B) Schematic illustration showing the structure of the nanomotorwith eGFP-gp16. C) eGFP-gp16 purified by His-tag affinity chromatography (10% SDS-PAGE). Lane 1: Molecular-weight protein marker. Lanes 2 and 3: E. coli BL21(DE3) with the pET32-eGFP-gp16 uninduced and induced by IPTG, respectively. Lanes 4 and 5: soluble cell extracts containing over-expressed eGFP-gp16 before and after passage through an affinity chromatography column, respectively. Lane 6: purified eGFP-gp16.
