DNA Polymerase I catalyzes the template-directed polymerization of nucleotides into duplex DNA in a 5'-->3' direction. DNA Polymerase I possesses a 3'-->5' exonuclease activity or proofreading function, which lowers the error rate during DNA replication, and also contains a 5'-->3' exonuclease activity, which enables the enzyme to replace nucleotides in the growing strand of DNA by nick translation. The enzyme, purified from recombinant E. coli, is capable of catalyzing de novo synthesis of synthetic homopolymers and provides a convenient method for the preparation of a variety of defined DNA substrates.
