WebAug 30, 1991 · Abstract. The 3 angstrom resolution crystal structure of the Escherichia coli catabolite gene activator protein (CAP) complexed with a 30-base pair DNA sequence shows that the DNA is bent by 90°. This bend results almost entirely from two 40° kinks that occur between TG/CA base pairs at positions 5 and 6 on each side of the dyad axis of … WebSep 30, 2024 · Two main strategies have been exploited to generate Cas9 variants with improved specificity. One is structure-guided protein engineering to modify amino acid residues in close contact with the target DNA strand or those interacting with the nontarget DNA strand (9–11).The other is through random mutagenesis followed by end-point …
