Mutant B-type DNA polymerases exhibiting improved performance in PCR

摘要

The present invention relates to thermostable mutants of B-type DNA polymerases comprising a Y-GG/A amino acid motif between the N-terminal 3′-5′-exonuclease domain and the C-terminal polymerase domain whereas the tyrosine of the Y-GG/A amino acid motif is mutated and whereas these mutant DNA polymerases are suitable for PCR.
