Designed Protein Pores as Components for Biosensors.

摘要

A mutant staphylococcal alpha hemolysin polypeptide containing a heterologous analyte-binding amino acid which assembles into an analyte-responsive heptameric pore assembly in the presence of a wild type staphylococcal alpha hemolysin polypeptide, digital biosensors, and methods of detecting, identifying, and quantifying analytes are described.
