Abstract
High yield purification of Ulp1 is required during the isolation and purification of SUMO-tagged recombinant proteins. However, when expressed as a soluble protein, Ulp1 is toxic to E. coli host cells and most of the protein forms inclusion bodies. The extraction of insoluble Ulp1 followed by its purification and refolding into its active form is a lengthy and costly procedure. In our present study, we developed a simple, cost effective procedure for the large scale production of active Ulp1 that can be used for industrial scale requirements.
