    摘要: Provided are methods for sequencing a nucleic acid with a sequencing enzyme, e.g., a polymerase or exonuclease. The sequencing enzyme can optionally be exchanged with a second sequencing enzyme, which continues the sequencing of the nucleic acid. In certain embodiments, a template is fixed to a surface through a template localizing moiety. The template localizing moiety can optionally anneal with the nucleic acid and/or associate with the sequencing enzyme. Also provided are compositions comprising a nucleic acid and a first sequencing enzyme, which can sequence the nucleic acid and optionally exchange with a second sequencing enzyme present in the composition. Compositions in which a template localizing moiety is immobilized on a surface are provided. Also provided are methods for using data from analytical reactions wherein two different enzymes are employed, e.g., at a same or different reaction regions.

    摘要: Provided are compositions comprising recombinant DNA polymerases that include amino acid substitutions, insertions, deletions and/or heterologous or exogenous features that confer modified properties upon the polymerase for enhanced single molecule sequencing. Such properties can include reduced reaction rates at one or more steps of the polymerase kinetic cycle, increased closed polymerase/DNA complex stability, enhanced metal ion coordination, reduced exonuclease activity, decreased branching fractions, and the like. Polymerases that exhibit branching fractions that are less than the branching fractions of the polymerases from which they were derived, or branching fractions that are less than about 25% for a phosphate-labeled nucleotide analog, are also provided. Also provided are nucleic acids which encode the polymerases with the aforementioned phenotypes, as well as methods of using such polymerases to make a DNA or to sequence a DNA template.
