Abstract

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. 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.
