Expression of yeast deubiquitination enzyme UBP1 analogues in E. coli

Background It has been shown that proteins fused to ubiquitin undergo greater expression in E. coli and are easier to purify and renaturate than nonhybrid foreign proteins. However, there is no commercial source of large quantities of specific deubiquitinating proteases. This is the reason why hybrid proteins containing ubiquitin at their N-end cannot be used in large scale biotechnological processes.
