Design Notes

The featured N-terminal His-tag makes it easy for all future iGEM teams to purify the construct using Ni-NTA affinity chromatography.

For any metal nanoparticles built inside of BFR it would be beneficary to remove any heme groups in order to prevent unloading of BFR by heme-mediated electron transfer. We constructed such a improved biobrick BBa_K1438001
