Key Concepts: Bacterial DNA polymerase I enzymes are multidomain proteins with separate polymerisation, proofreading and 5â²â3â² exonuclease functions. They perform a vital function in bacteria by carrying out DNA repair and some aspects of chromosomal replication.
Enzymes such as NDM-1 are produced by strands of DNA which bacteria are known to transfer between one another. Currently two bacteria have been host to the NDM-1 enzyme: Escherichia coli and Klebsiella pneumonia (above), both of which are found in the human gut and are normally harmless.
