exonucleases

Exonucleases are enzymes that work by cleaving nucleotides one at a time from the end (exo) of a polynucleotide chain. A hydrolyzing reaction that breaks ...

Exonucleases often act redundantly in biological functions of RNA processing and degradation, mutation avoidance, and in DNA repair and recombination. Therefore ...

2022年4月19日 — Exonucleases mainly function in the control of genetic quality, DNA proofreading during replication, homologous combination, and DNA repair.

由 J Manils 著作 · 2022 · 被引用 5 次 — Exonucleases are involved in central pathways of cell biology such as DNA replication, repair, and death, as well as tuning the immune response.

由 PA Mason 著作 · 2012 · 被引用 46 次 — Exonucleases are key enzymes involved in many aspects of cellular metabolism and maintenance and are essential to genome stability, acting to cleave DNA ...

2019年10月24日 — Exonucleases are enzymes that catalyze the removal of nucleotides in either the 5´ to 3´ or the 3´ to 5´ direction from the ends of ...

2020年7月22日 — Both endonuclease and exonuclease are nuclease enzymes which can hydrolyze polynucleotide chains such as DNA and RNA.

外切酶，或核酸外切酶（英語：exonucleases）可以是單獨存在的酶，或是大型酶複合物的一部分。此類酶能將聚核苷酸鏈分解成核苷酸。作用方式是將3'或5'端上的磷酸酯鍵 ...
