FTP, identify this enzyme that catalyzes, from a template model, the replication of DNA.
It was first isolated in 1957 by Arthur Kornberg and colleagues.  In 1969, Peter DeLucia and John Cairns reported the discovery of a mutant strain of E. coli that was deficient in it, which they offered as the reason for the strain's inability to repair UV-induced damage.  So far two types of the number one variety have been discovered, and it is known that all three types possess exonuclease activity in the 3 prime to 5 prime direction.
