Abstract
A ubiquitin hydrolase is provided having a purity of at least 70% homogeneity based on the weight of the total protein in the composition. Also provided are DNA sequences encoding ubiquitin hydrolases, as well as expression systems for their recombinant production. Processes are provided for purification of a ubiquitin hydrolase from eukaryotes and for its use in recovering any desired polypeptide free from its fusion at its N-terminus with ubiquitin.
