Disclosed herein are modified polymerase compositions exhibiting altered polymerase activity, which can be useful in a variety of biological applications. Also disclosed herein are methods of making and using such compositions. In some embodiments, the compositions exhibit altered properties that can enhance their utility in a variety of biological applications. Such altered properties, can include, for example, altered nucleotide binding affinities, altered nucleotide incorporation kinetics, altered photostability and/or altered nanoparticle tolerance, as well as a range of other properties as disclosed herein.

Polymerase compositions and methods

Provided herein are compositions and systems for use in polymerase-dependent, nucleotide transient-binding methods. The methods are useful for deducing the sequence of a template nucleic acid molecule and single nucleotide polymorphism (SNP) analyses. The methods rely on the fact that the polymerase transient-binding time for a complementary nucleotide is longer compared to that of a non-complementary nucleotide. The labeled nucleotides transiently-binds the polymerase in a template-dependent manner, but does not incorporate. The methods are conducted under any reaction condition that permits transient binding of a complementary or non-complementary nucleotide to a polymerase, and inhibits nucleotide incorporation.

Nucleotide transient binding for sequencing methods

Provided herein are mutant DNA-dependent polymerases which are derived from, or otherwise related to, wild type RB69 DNA polymerase. These mutant polymerases are capable of selectively binding labeled nucleotides. These mutant polymerases are also capable of incorporating a variety of naturally occurring and modified nucleotides, including, for example, terminator nucleotides.
