First Claim
Patent Images
1. A DNA polymerase having increased 3′
- -mismatch discrimination activity compared with a control DNA polymerase, wherein the amino acid of the DNA polymerase corresponding to position 667 of SEQ ID NO;
1 is any amino acid other than V or I, and wherein the control DNA polymerase has the same amino acid sequence as the DNA polymerase except that the amino acid of the control DNA polymerase corresponding to position 667 of SEQ ID NO;
1 is V or I.

Abstract
Disclosed are mutant DNA polymerases having increased 3′-mismatch discrimination relative to a corresponding, unmodified polymerase. The mutant polymerases are useful in a variety of disclosed primer extension methods. Also disclosed are related compositions, including recombinant nucleic acids, vectors, and host cells, which are useful, e.g., for production of the mutant DNA polymerases.
