  • Publication number: 20240010688
    Abstract: The present disclosure provides variant OmpG polypeptides, compositions comprising the OmpG variant polypeptides, and methods for using the variant OmpG polypeptides as nanopores for determining the sequence of single stranded nucleic acids. The variant OmpG nanopores reduce the ionic current noise versus the parental OmpG polypeptide from which they are derived and thereby enable sequencing of polynucleotides with single nucleotide resolution. The reduced ionic current noise also provides for the use of these OmpG nanopore variants in other single molecule sensing applications, e.g., protein sequencing.

  • Publication number: 20200216887
    Abstract: A method is provided for preparing nanopore sequencing complexes in membranes for sequencing of polymers, e.g., polynucleotides and polypeptides. The nanopore sequencing complex is formed by the sequential linking of an enzyme to a nanopore that is inserted in a membrane, and of a polymer to the enzyme. Alternatively, the nanopore sequencing complex is formed by linking a preformed enzyme-polymer complex to a nanopore that is inserted in a membrane. The enzyme polymer complex is interchangeable.
