title: Protein products synthesized by a cloned viral protease gene.
abstract: A region of the poliovirus genome coding for a cysteine protease was expressed in E. coli. Following separation in isoelectric focussing gels, four new proteins were identified and were shown to be products of the viral cDNA. Although a majority of the protein products is aggregated, the system offers the first practical basis for production of large quantities of a viral protease.
