This crRNA binds to 【the CRISPR repeats on the messenger RNA】, and thenthe messenger RNA will be chopped up by Cas9 and another enzyme called RNase III And we will end up with these pieces of RNA *This is the crRNA in type 2* (crRNA = spacer DNA + CRISPR sequence + tracr RNA)【...
and resulting in RNA-DNA pairing when a matching sequence is present [1,2]. Cas9 nucleases with alternative PAMs have also been characterized and successfully used for genome editing [3]. It is important to note that the PAM is not present in the crRNA sequence but needs to be immediately...
The pre-crRNA is processed into shorter crRNA molecules each containing a spacer and a part of the repeat sequence. Finally, interference can occur, after the crRNA forms a complex with the effector protein, forming a functional RNA guided endonuclease. This endonuclease is guided by the crRNA, ...

当噬菌体感染细菌后,病毒DNA进入细菌细胞,细菌细胞表达Cas复合体对噬菌体DNA进行切割得到间隔序列,间隔序列在cas1 和cas2作用下插入到CRISPR最前端(如图1)形成免疫。当噬菌体再次感染细菌时,以Type II型CRISPR/Cas系统为例,细菌表达 tracrRNA、前体crRNA及Cas9蛋白(RNA引导的核酸内切酶),tracrRNA和crRNA由于部分序列互补...
当噬菌体再次感染细菌时,以Type II型CRISPR/Cas系统为例,细菌表达 tracrRNA、前体crRNA及Cas9蛋白(RNA引导的核酸内切酶),tracrRNA和crRNA由于部分序列互补而结合,Cas9与tracrRNA和crRNA形成复合体并由Cas9加工成为成熟crRNA-tracrRNA Cas9复合体,成熟复合体由间隔序列引导识别病毒靶序列,并切断病毒DNA。复合体只能识别与间隔...
