After elucidating key steps in the pathways of pyrimidine and purine nucleotide synthesis, including the discovery of 5′-phosphoribosyl-1-pyrophospate (PRPP) as an …
The following year, Thomas Kornberg and Gefter reported the identification of what became DNA polymerase III of E. coli 22, the true replicative polymerase. The enzyme discovered by Arthur...
His discovery of DNA polymerase I (Bessman et al. 1958; Lehman et al. 1958a) and his demonstration that it faithfully copies the base sequence of a template DNA strand (Lehman et …
Kornberg's group isolated DNA polymerase from E. coli bacteria. When he added the protein to a tube of salt solution containing DNA molecules and nucleotide building blocks, it was able to synthesize new strands of DNA.
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, not RNA, could be retrieved. To initiate the purification of DNA polymerase, the researchers added streptomycin sulfate to the E. coli extract. This separated the extract into a nucl…
The review demonstrates that structural comparison of DNA polymerase architecture suggests a nucleotide gateway to the polymerase active site.
While studying E. coli bacteria, enzymologist Arthur Kornberg discovered that DNA polymerases catalyze DNA synthesis. Kornberg's experiment involved mixing all of the basic "ingredients"...
