The invention relates to mutant forms of CsgG. The invention also related to analyte detection and characterisation using CsgG.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus comprising a transmembrane protein pore inserted into an in vitro membrane, wherein the transmembrane protein pore comprises at least one CsgG monomer having amino acid mutations at two or more positions corresponding to Y51, N55, and F56 of the sequence shown in SEQ ID NO: 390. 2. The apparatus of claim 1 , wherein the at least one CsgG monomer comprises mutations at positions corresponding to Y51/N55, Y51/F56, N55/F56 or Y51/N55/F56. 3. The apparatus of claim 1 , wherein the at least one CsgG monomer comprises mutations corresponding to F56N/N55Q, F56N/N55R, F56N/N55K, F56N/N55S, F56N/N55G, F56N/N55A, F56N/N55T, F56Q/N55Q, F56Q/N55R,
