MUTANT NANOARCHAEUM EQUITANS A523R DNA POLYMERASE AND ITS USE

摘要

Disclosed herein is a mutant Neq A523R DNA polymerase consisting of an amino acid sequence of SEQ ID NO: 2 wherein alanine at amino acid position 523 in a Nanoarchaeum equitans DNA polymerase (Neq DNA polymerase) consisting of an amino acid sequence of SEQ ID NO: 1 has been substituted with arginine by site-directed mutagenesis. Also disclosed are a gene consisting of a nucleotide sequence encoding the mutant Neq A523R DNA polymerase, a recombinant vector comprising the gene, and a transformant transformed with the vector. In addition, disclosed are a PCR kit comprising the mutant Neq A523R DNA polymerase having excellent performance compared to the wild-type Neq DNA polymerase, and a method for preparing the Neq A523R DNA polymerase.
