  • POL6 POLYMERASE VARIANTS
    Publication number: 20210071152
    Abstract: The present disclosure provides variant Pol6 polymerase polypeptides, compositions comprising the Pol6 variant polypeptides, and methods for using the variant Pol6 polypeptides for determining the sequencing of nucleic acids, for example, by nanopore sequencing. The variant Pol6 polymerases possess decreased rates of dissociation of template from the polymerase-template complex, which result in increased processivity relative to the parental Pol6 polypeptides from which they are derived.
