Dna i polymerase
DNA polymerase I (or Pol I) is an enzyme that participates in the process of prokaryotic DNA replication. Discovered by Arthur Kornberg in 1956, it was the first known DNA polymerase (and the first known of any kind of polymerase). It was initially characterized in E. coli and is ubiquitous in prokaryotes. … See more In 1956, Arthur Kornberg and colleagues discovered Pol I by using Escherichia coli (E. coli) extracts to develop a DNA synthesis assay. The scientists added C-labeled thymidine so that a radioactive polymer of DNA, … See more In the replication process, RNase H removes the RNA primer (created by primase) from the lagging strand and then polymerase I fills in the necessary nucleotides between … See more • DNA polymerase II • DNA polymerase III • DNA polymerase V See more General structure Pol I mainly functions in the repair of damaged DNA. Structurally, Pol I is a member of the alpha/beta protein superfamily, which encompasses proteins in which α-helices and β-strands occur in irregular sequences. See more DNA polymerase I obtained from E. coli is used extensively for molecular biology research. However, the 5'→3' exonuclease activity makes it unsuitable for many … See more WebDNA Polymerase I is a DNA polymerase with 5´→3´ and 3´→5´ exodeoxyribonuclease activities. DNA Polymerase I also incorporates biotinylated nucleotides. • Applications —DNase I-dependent nick translation, second-strand synthesis in cDNA cloning, fill-in of 5´ overhangs. • Source —purified from E. coli expressing the DNA ...
