WebFeb 4, 2024 · CRISPR-Cas systems present in the family Vibrionaceae. Using BLAST and comparative genome analyses, we examined species belonging to the family Vibrionaceae available in the NCBI genome database for the presence of CRISPR-Cas systems. We identified eight different system types: type I-C, I-E, I-F, II-B, III-A, III-B, III-D, and IV as … WebUpon target binding, degradation of the foreign DNA occurs with the help of other nucleases. In the type I-C system, an additional factor known as Cas4 forms a higher-order adaptation complex with the conserved Cas1-Cas2 integration complex. Previous studies in our lab have shown that Cas4 is required for PAM recognition and cleavage in vitro.
