An improved miniprotein host for fluorogenic supramolecular assembly on the surface of living cells

摘要

An improved miniprotein host capable of fluorogenic supramolecular assembly with a sI-Pht guest is reported. This improved host, termed 6.2.22, displays significant enhancements in both the EC _(50) for complexation and fluorescence activation of the sI-Pht guest, allowing for improved resolution of supramolecular complexation on the surface of living yeast.
