Provided are nucleic acids encoding engineered polymerases comprising at least one modification in a motif A and/or at least one modification in a motif B of the polymerase and engineered polymerases encoded by the nucleic acids. Also provided are engineered DNA polymerases comprising a variant of SEQ ID NO:1, SEQ ID NO:2, or SEQ ID NO:3, the variant being at least 80% identical to SEQ ID NO:1, SEQ ID NO:2 or SEQ ID NO:3 and comprising an amino acid substitution at one or more positions selected from the group consisting of L408, Y409, P410, R484, A/L485, and I486. Methods, vectors, kits, and compositions comprising the nucleic acids and compositions, methods and kits comprising the engineered polymerases are also provided. |
