First claim

Opening claim text (preview).

What is claimed is: 1. A modified DNA polymerase having a DNA polymerase activity comprising an amino acid sequence having at least 95% sequence identity to the amino acid sequence as set forth in SEQ ID NO: 2, which amino acid sequence includes an amino acid substitution corresponding to H527Y/T/M, wherein said modified DNA polymerase has an altered characteristic compared to a parental polymerase. 2. The modified DNA polymerase of claim 1 , wherein the altered characteristic is selected from fidelity, processivity, elongation rate, stability, solubility and the ability to bind and/or incorporate polyphosphate nucleotides selected from a tetraphosphate, pentaphosphate, hexaphosphate, heptaphosphate or octophosphate nucleotide. 3. The modified DNA polymerase of claim 1 , wherein the altered characteristic is the ability to incorporate a nucleotide polyphosphate having 4, 5, 6, 7 or 8 phosphates into a growing DNA strand. 4. The modified DNA polymerase of claim 3 , wherein the nucleotide polyphosphate is tagged. 5. The modified DNA polymerase of claim 1 , wherein said polymerase comprises less than 10 mutations. 6. The modified DNA polymerase of claim 1 , wherein the parental polymerase has an amino acid sequence consisting of SEQ ID NO: 1. 7. The modified DNA polymerase of claim 1 , wherein the parental polymerase has an amino acid sequence consisting of SEQ ID NO: 2.
