Abstract
DNA polymerase pol is a ubiquitous enzyme that synthesizes DNA strands in all living cells In vitro DNA pol is used for DNA manipulation including cloning PCR sitedirected mutagenesis sequencing and several other applications Family B archaeal DNA pols have been widely used for molecular biological methods Biochemical and structural studies reveal that each archaeal DNA pol has different characteristics with respect to fidelity processivity and thermostability Due to their high fidelity and strong thermostability family B archaeal DNA pols have the extensive application on highfidelity PCR DNA sequencing and sitedirected mutagenesis while family Y archaeal DNA pols have the potential for errorprone PCR and random mutagenesis because of their low fidelity and strong thermostability This information combined with mutational analysis has been used to construct novel DNA pols with altered properties that enhance their use as biotechnological reagents In this review we focus on the development and use of family B archaeal DNA polsWe thank Prof A Steinbüchel for his support in this review We also thank Prof Linda J RehaKrantz for the critical reading of our manuscript Research in Dr Likui Zhang’s laboratory was supported by the National Natural Science Foundation of China grant No 41306131 the Provincial Natural Science Foundation of Jiangsu China grants Nos BK20130440 and 13KJB180029 the open project of State Key Laboratory of Microbial Resources No SKLMR20130603 the Openend Funds of Jiangsu Key Laboratory of Marine Biotechnology Huaihai Institute of Technology No 2014HS008 and the Yangzhou University College Student Science and Technology Innovation grant
