FAQ: Is the rate of TEV Protease cleavage affected by urea or guanidine hydrochloride?

The activity of TEV Protease on an MBP-fusion protein in the presence of these denaturants has been reported by C. Sun et al. as follows: Urea: In up to 2 M urea near complete cleavage is detected. There is some inhibition of TEV Protease cleavage in urea concentrations of 4 M. Guanidine HCl: 1 M guanidine HCl yields slight inhibition of TEV Protease cleavage; however, some TEV Protease activity is still observed in the presence of 3 M guanidine HCL.
