en·do·nu·cle·ase E0136000 (ĕn′dō-no͞o′klē-ās′, -āz′, -nyo͞o′-)n. Any of a group of enzymes that catalyze the hydrolysis of bonds between nucleotides in the interior of a DNA or RNA molecule.endonuclease (ˌɛndəʊˈnjuːklɪˌeɪz) n (Biochemistry) an enzyme that is responsible for scission of a nucleic acid chain, the action of which is not confined to the terminal nucleotide. Compare exonucleaseen•do•nu•cle•ase (ˌɛn doʊˈnu kliˌeɪs, -ˌeɪz, -ˈnyu-)
n. any of a group of enzymes that degrade DNA or RNA molecules by breaking linkages within the polynucleotide chains. [1960–65] Thesaurus| Noun | 1. | endonuclease - a nuclease that cleaves nucleic acids at interior bonds and so produces fragments of various sizesnuclease - general term for enzymes that catalyze the hydrolysis of nucleic acid by cleaving chains of nucleotides into smaller unitsrestriction endonuclease, restriction enzyme, restriction nuclease - any of the enzymes that cut nucleic acid at specific restriction sites and produce restriction fragments; obtained from bacteria (where they cripple viral invaders); used in recombinant DNA technology |
