caption_attribution_description: English: The X-ray crystal structure of exonuclease III from Escherichia coli. The multifunctional enzyme performs DNA repair activities, including 3'-repair diesterase, 3' to 5' exonuclease, 3'-phosphomonoesterase, and ribonuclease activities. The structure was solved to a resolution of 1.70 Å.
context_page_description: Exonuclease III is an enzyme that belongs to the exonuclease family. ExoIII catalyzes the stepwise removal of mononucleotides from 3´-hydroxyl termini of double-stranded DNA. A limited number of nucleotides are removed during each binding event, resulting in coordinated progressive deletions within the population of DNA molecules.
