Enzyme that degrades a nucleic acid from the ends, cleaving off one nucleotide at a time.

An enzyme that cleaves DNA at the free 5' or 3' ends by breaking the phosphodiester bonds of the backbone.

A nuclease that catalyzes sequential cleavage of nucleotides from the 5' or 3' end of a polynucleotide chain.

An enzyme which digests nucleic acids starting at one end. An example is Exonuclease III, which digests only double-stranded DNA starting from the 3' end.

a nuclease that releases one nucleotide at a time (serially) beginning at one of a nucleic acid

enzyme that cleaves nucleotides from one end of a strand of nucleic acid.

An enzyme that removes individual nucleotides from the end of single- or double-stranded DNA, usually specific for a 3´ or 5´ end.

An enzyme that breaks down nucleic acids only at the ends of polynucleotide chains, thus releasing one nucleotide at a time, in sequential order. Cf. Endonuclease

an enzyme that digests DNA, beginning at the ends of the strands

nuclease that sequentially removes nucleotides from one end of a strand of nucleic acid. ( 16)

An enzyme that cleaves nucleotides sequentially from free ends of a linear nucleic acid substrate.

An enzyme which cleaves nucleotides sequentially starting at the free end of the linear chain of DNA.

An enzyme that sequentially removes nucleotides from the ends of a nucleic acid molecule.

Exonucleases are enzymes that cleave nucleotides one at a time from an end of a polynucleotide chain. These enzymes hydrolyze phosphodiester bonds from either the 3' or 5' terminus of polynucleotide molecules.
