Title
(EN) NOVEL DNA POLYMERASE
Abstract
(EN)

Provided are various novel DNA polymerases.

Provided are: a DNA polymerase comprising: an amino acid sequence modified from the amino acid sequence of SEQ ID NO: 12, which has a substitution of arginine at position 651 by an amino acid residue having a negatively charged side chain, preferably by asparatic acid or glutamic acid, more preferably by glutamic acid; and a DNA polymerase comprising an amino acid sequence modified from the amino acid sequence of SEQ ID NO: 14, which has a substitution of proline at position 653 by an amino acid residue having a negatively charged side chain, preferably by asparatic acid or glutamic acid, more preferably by glutamic acid.
