Recombinant His-tagged DNA polymerase. II. Cloning and purification of Thermus aquaticus recombinant DNA polymerase (Stoffel fragment).

Acta Biochim Pol (1998), Volume 45, Page 661

Abstract:

The Stoffel DNA fragment, shortened by 12 bp from 5' end, coding for Stoffel DNA polymerase (missing 4 amino acids at N-terminus of Stoffel amino-acids sequence) from the thermophilic Thermus aquaticus (strain YT-1) was amplified, cloned and expressed in Escherichia coli. The recombinant Stoffel fragment contained a polyhistidine tag at the N-terminus (21 additional amino acids) that allowed its single-step isolation by Ni2+ affinity chromatography. The enzyme was characterized and displayed high DNA polymerase activity and thermostability evidently higher than the native Taq DNA polymerase.
