Exonucleases (ExN) cleave nucleotides at the end of a polynucleotide chain. In E. coli there are ExN I to VIII. ExN-I cleaves single-stranded DNA; ExN-II is associated with DNA polymerase; ExN-III cleaves double-stranded DNA; ExN-IV cleavage results in nucleoside monophosphate; ExN-V cleaves linear double-stranded DNA; ExN-VIII requires a free 5’ OH group for reacting. ExN were found in human and yeast as well.
