TEV protease tagged with mCherry

A non-self-cleaving TEV protease sequence with an N terminal mCherry tag and a C terminal His tag. The fluorophore tag allows for relative quantification of expression. The His tag allows for purification using a nickel column.

Usage and Biology

TEV protease is a well-characterised specific protease from the Tobacco Etch Virus, with a cleavage sequence of Glu-Asn-Leu-Tyr-Phe-Gln-(CUT)-Gly.

This is a non-self-cleaving protease as we wanted a constant level of TEV protease produced.

We have used TEV protease as both a substitute for cruzipain, another specific protease, and as a signal amplifier after simulated cruzipain cleavage.

This part does not require any other parts to be functional.
