dc.description.abstract | Genomic analysis of a hyperthermophilic archaeon Thermococcus NA1(TNA1) revealed the presence of an open reading frame consisting of 468 bp similar to dUTPases from Pyrococcus woesei and P. furiosus (83% identity and 93% similarity). TNA1 dUTPase has five motifs conserved in all dUTPases from eukarya and prokarya origins. The dUTPase gene was cloned and expressed in Escherichia coli. The purified protein behaved as a dimer in gel filtration chromatography and was able to hydrolyze both dUTP and dCTP. The optimum activity toward dUTP occurred at 80 °C and pH 8.0. Moreover, the enzyme activity was highly dependent on Mg2+ concentration with optimum activity at 1mM to 5mM which is usually used at PCR amplification. The activity was not affected by KCl and (NH4)2SO4 while Tritoxn X-100 slightly increased dUTPase activity. The enzyme displayed thermostability with half-life (t1/2) of 170 min at 95 °C. TNA1 dUTPase enhanced the PCR performance of family B type DNA polymerase in a broader range of target lengths. | - |
