Abstract

Compositions that include polymerases with features for improving entry of nucleotide analogs into active site regions and for coordinating with the nucleotide analogs in the active site region are provided. Methods of making the polymerases and of using the polymerases in sequencing and DNA replication and amplification as well as kinetic models of polymerase activity and computer-implemented methods of using the models are also provided.
