Variants targeting a sequence within the Anopheles AGAP004734 gene were created from the recently characterized I-OnuI endonuclease, … WebHoming endonucleases are double stranded DNases that have large, asymmetric recognition sites (12-40 base pairs) and coding sequences that are usually embedded in either introns or inteins (1). Introns are spliced out of precursor RNAs, while inteins are spliced out of precursor proteins (2,3). Homing endonucleases are named using …

Web7 apr. 2014 · Phage terminases are composed of two proteins: the large subunit harbors an endonuclease domain and an ATPase that powers the DNA packaging reaction, and the small subunit mediates specific DNA-binding required for recognition of packaging sites in the phage genome. WebI-CreI is a homing endonuclease whose gene was first discovered in the chloroplast genome of Chlamydomonas reinhardtii, a species of unicellular green algae. [1] It is named for the facts that: it resides in an I ntron; it was isolated from Clamydomonas reinhardtii; it was the first ( I) such gene isolated from C. reinhardtii.
