DNA encoding ricin A chain was derived from preproricin cDNA and ligated into the expression vector pDS5/3. Transcription is controlled from the coliphage promoter PN25 fused with the lac operator of E.coli. When induced, E.coli 71.18 cells transformed with the recombinant plasmid express ricin A chain which is soluble and has full biological activity.
