Abstract:S-Adenosylhomocysteine hydrolase gene of amphioxus Branchiostoma belcheri tsingtaunese was induced to express the fusion protein in E. coli. Amphioxus SAHH gene was cloned into a bacterial expression vector pGEX-6P-1 and the recombinant plasmid pGEX-6P-1-SAHH was transferred into E. coli JM109. The GST-SAHH was induced by IPTG, and the fusion protein was purified by affinity purification. The molecular mass of fusion protein GST-SAHH was estimated to be approximately 70 kDa by SDS-PAGE electrophoresis. A prokaryotic expression plasmid containing amphioxus SAHH gene was successfully constructed, and it could be effectively purified by the GST affinity column.
