Fusion of Taq DNA polymerase with single-stranded DNA binding-like protein of Nanoarchaeum equitans—Expression and characterization
DNA polymerases are present in all organisms and are important enzymes that synthesise DNA molecules. They are used in various fields of science, predominantly as essential components for in vitro DNA syntheses, known as PCR. Modern diagnostics, molecular biology and genetic engineering need DNA polymerases which demonstrate improved performance. This study was aimed at obtaining a new NeqSSB-T...
متن کاملCharacterization of a Single-Stranded DNA-Binding-Like Protein from Nanoarchaeum equitans—A Nucleic Acid Binding Protein with Broad Substrate Specificity
BACKGROUND SSB (single-stranded DNA-binding) proteins play an essential role in all living cells and viruses, as they are involved in processes connected with ssDNA metabolism. There has recently been an increasing interest in SSBs, since they can be applied in molecular biology techniques and analytical methods. Nanoarchaeum equitans, the only known representative of Archaea phylum Nanoarchaeo...
متن کاملCharacterization of a mitochondrial protein binding to single-stranded DNA.
A DNA-binding protein from Xenopus laevis oocyte mitochondria which has been found associated with the D-loop also shows a strong preference for single-stranded DNA. The binding to polynucleotides is dependent on the base composition, but no sequence specificity was found. This protein, called mtSSB, binds tightly and cooperatively to single-stranded DNA. By its amino-acid composition and its b...
متن کاملBinding of the dimeric Deinococcus radiodurans single-stranded DNA binding protein to single-stranded DNA.
Deinococcus radiodurans single-stranded (ss) DNA binding protein (DrSSB) originates from a radiation-resistant bacterium and participates in DNA recombination, replication, and repair. Although it functions as a homodimer, it contains four DNA binding domains (OB-folds) and thus is structurally similar to the Escherichia coli SSB (EcoSSB) homotetramer. We examined the equilibrium binding of DrS...
متن کاملPurification of DNA polymerase II stimulatory factor I, a yeast single-stranded DNA-binding protein.
Incidental to the purification of yeast DNA polymerase II was the observation that various chromatographic fractions contained activities that stimulated synthesis by this polymerase. In this paper we report the purification and initial characterization of one such factor, stimulatory factor I (SFI). SFI, which is associated with an apparent complex of three polypeptides of 66, 37, and 13.5 kDa...
