Title:
AN ELP FUSION PROTEIN AND USES THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/063172
Kind Code:
A1
Abstract:
Provided are a fusion protein comprising ELP and uses thereof, and ELP-tagged protease that can be used as recycling utilized enzyme with immobilized enzyme characteric and uses thereof. For example, the purification or seperation method using of phase transition characteristic of ELP comprises contacting the ELP fusion protein having protease cleavage site with ELP-tagged enzyme, then subjecting the cleavage mixture to phase transition mediated by changing temperature, pH or salt ionic concentration to recover the protein of interest from the cleavage mixture.
