WebIn the type II CRISPR system, RNase III cleaves an RNA duplex formed by the CRISPR repeat and a trans-activating CRISPR RNA (tracrRNA) (Deltcheva et al, 2011), while in the type I and type III systems, a CRISPR- ... Csy4 is a 21.4kDa protein that recognizes its RNA substrate via sequence- and structure-specific contacts. It cleaves cog- WebThe Csy4 active site lacks a general acid to protonate the leaving group and positively charged residues to stabilize the transition state, explaining why the observed catalytic rate constant is ~10 4-fold slower than that of RNase A. The RNA cleavage step carried out by Csy4 is essential for assembly of the Csy protein-crRNA complex that ...
