First claim

Opening claim text (preview).

What is claimed is: 1. An isolated polypeptide having a DNA polymerase activity comprising an amino acid sequence having at least 95% sequence identity to SEQ ID NO: 1, wherein the amino acid sequence having at least 95% sequence identity to SEQ ID NO: 1 comprises at least two amino acid substitutions relative to SEQ ID NO: 2, wherein one of said at least two amino acid substitutions corresponds to position T529 of SEQ ID NO: 2. 2. The isolated polypeptide of claim 1 , wherein the T529 substitution is a T529M/F substitution. 3. The isolated polypeptide of claim 1 , wherein said isolated polypeptide has a substitution corresponding to T529M. 4. The isolated polypeptide of claim 1 , wherein said at least two amino acid substitutions comprises a set of substitutions selected from the group consisting of: T529M+T647G+A547F; T529M+A610T+A547F; M641Y+T529M+A547F; N535L+N545K+T651Y+T529M; and N535I+N545K+T651Y+T529M. 5. The isolated polypeptide of claim 1 , wherein said polymerase comprises less than 10 mutations. 6. The isolated polypeptide of claim 1 , wherein at least one of the at least two corresponds to a position of SEQ ID NO: 2 selected from the group consisting of selected from the group consisting of Y225, M531, N535, G539, N545, A547, N552, A610, M641, Y629, T647, T651, I652, K655, D657, V658. 7. The isolated polypeptide of claim 1 , wherein at least one of the at least two substitutions is selected from the group consisting of selected from the group consisting of Y225L/T/I/F/A, M531H/Y/A/K/R/W/T/L/V, N535L/Y/M/K/I, G539Y/F, N545K/D/S/L/R, A547M/Y/W/F/V/S, N552L/M/S, A610T/E, M641L/Y, Y629 W/H/M, T647G/A/E/K/S, T651Y/F/M, I652Q/G/S/N/F/T, K655G/F/E/N, D657R/P/A, and V658L.
