Web12 jan. 2011 · Homing endonucleases are microbial DNA-cleaving enzymes that mobilize their own reading frames by generating double strand breaks at specific genomic invasion sites. These proteins display an economy of size, and yet recognize long DNA sequences (typically 20 to 30 base pairs). WebEngineered Meganucleases/Homing Endonucleases. Meganucleases are sequence-specific endonucleases that use large (414 bp) recognition sites to generate accurate double-strand breaks (DSBs), promoting efficient gene targeting through homologous recombination (HR). Their recognition sites are extremely rare, and in a mammalian …
