In e. coli, the function of DNA polymerase iii is directly involved in DNA replication.

In the bacterium E. coli Arthur Kornberg found three different DNA polymerases:

  • DNA polymerase I.

  • DNA polymerase II.

  • DNA polymerase III.

E. coli DNA Polymerases can only synthesize (polymerize) DNA in the 5'P-3'OH direction.

DNA polymerase III and DNA polymerase I are the enzymes that are directly involved in the replication of E. coli DNA.

  • DNA polymerase I has a repairing role, it removes primers with its 5'-3 'exonuclease activity and fills the gap with its 5'-3' polymerrase activity.

  • DNA polymerase II  is exclusively assigned a reparative function.

  • DNA polymerase III is the enzyme that performs the majority of DNA replication, the catalytic heart of the enzyme is made up of the subunits in charge of polymerization and performs the proofreading function.

The proofreading function is carried out by the DNA polymerase III where it removes the last nucleotide that the polymerase has incorrectly introduced, this function is called 3'-5 'exonuclease function.

Therefore, we can conclude that In e. coli, the function of DNA polymerase iii is directly involved in DNA replication.
