Expression of ricin B chain in Escherichia coli

FEBS Lett. 1989 Feb 27;244(2):383-7. doi: 10.1016/0014-5793(89)80568-x.

Abstract

DNA encoding ricin B chain was fused to that encoding the E. coli OmpA signal peptide using the expression secretion vector pIN-111-ompA. When induced, E. coli cells transformed with the recombinant plasmid express ricin B chain. The recombinant product accumulates in the periplasmic space in a soluble, biologically active form.
