Bilobed architecture
WebApr 21, 2016 · AsCpf1 adopts a bilobed architecture, with the RNA-DNA heteroduplex bound inside the central channel. The structural comparison of AsCpf1 with Cas9, a type II CRISPR-Cas nuclease, reveals both striking similarity and major differences, thereby explaining their distinct functionalities. In the available Cas9–RNA–DNA structures, the HNH domain adopts catalytically inactive conformations and is not located near the scissile phosphate in the target DNA … See more We first observed apo-Cas9 and pre-assembled Cas9–RNA on a mica surface treated with 3-aminopropyl-triethoxysilane (AP-mica). … See more We next sought to observe the target DNA cleavage by Cas9–RNA. To this end, we mixed pre-assembled Cas9–RNA with the target DNA in the absence of Mg2+, adsorbed the complex on the AP-mica surface, and then … See more We next sought to visualize the binding of Cas9–RNA to the target DNA. To avoid Mg2+-dependent DNA cleavage by Cas97, we incubated … See more Our HS-AFM movies revealed that most of the Cas9–RNA molecules remain bound to the PAM-distal region (the non-PAM side) of the cleaved DNA … See more
