exonuclease
exonuclease[¦ek·sō′nü·klē‚ās] (biochemistry) Any of a group of enzymes which catalyze hydrolysis of single nucleotide residues from the end of a deoxyribonucleic acid chain. exonuclease
exonuclease [ek″so-noo´kle-ās] an enzyme that cleaves single mononucleotides from the end of a polynucleotide chain.ex·o·nu·cle·ase (ek'sō-nū'klē-ās), A nuclease that releases one nucleotide at a time, serially, beginning at one end of a polynucleotide (nucleic acid); several have been prepared from Escherichia coli, designated exonuclease I, exonuclease II, etc.; exonuclease III, which removes nucleotides from 3' ends of DNA, is used in DNA sequencing. Compare: endonuclease. exonuclease (ĕk′sō-no͞o′klē-ās′, -āz′, -nyo͞o′-)n. Any of a group of enzymes that catalyze the hydrolysis of single nucleotides from the end of a DNA or RNA chain.ex·o·nu·cle·ase (eks'ō-nū'klē-ās) A nuclease that releases one nucleotide at a time, serially, beginning at one end of a polynucleotide (nucleic acid).
Compare: endonucleaseexonuclease an enzyme that removes a terminal NUCLEOTIDE (3' or 5') in a POLYNUCLEOTIDE CHAIN. Exonucleases remove the nucleotides in a successive way, one by one, and are highly specific in their action.ex·o·nu·cle·ase (eks'ō-nū'klē-ās) A nuclease that releases one nucleotide at a time, serially, beginning at one end of a polynucleotide (nucleic acid).
