    摘要: The present invention relates to a DNA polymerase possesses the properties of 1) exhibiting higher polymerase activity when assayed by using as a substrate a complex resulting from primer annealing to a single stranded template DNA, as compared to the case where an activated DNA is used as a substrate; 2) possessing a 3′→5′ exonuclease activity; 3) being capable of amplifying a DNA fragment of about 20 kbp, in the case where polymerase chain reaction (PCR) is carried out using &lgr;-DNA as a template. It also relates to a DNA polymerase-constituting protein; a DNA containing the base sequence encoding thereof; and a method for producing the DNA polymerase. The present invention provides a novel DNA polymerase possessing both a high primer extensibility and a 3′→5′ exonuclease activity.
