Claims21
-20. (canceled)
A ribonucleoprotein comprising a
- (a) Type I-E CRISPR associated complex for antiviral defense complex (Cascade complex) comprising one or more of a Cse1 polypeptide, a Cse2 polypeptide, a Cas7 polypeptide, a Cas5 polypeptide and/or a Cas6 polypeptide, and
- (b) a Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) array comprising two or more repeat sequences and one or more spacer sequence(s), wherein each of the one or more spacer sequences is linked at its 5′ end and at its 3′ end to a repeat sequence, and each of the one or more spacer sequences is complementary to one or more target sequences in a target DNA of a target organism, wherein the target DNA is located immediately adjacent (3′) to a protospacer adjacent motif (PAM), wherein the two or more repeat sequences comprise 20 to 28 consecutive nucleotides of a nucleotide sequences having at least 80% sequence identity to any one of the nucleotide sequences of SEQ ID NOs:1, 10, 19, 28, 37, 42, 51, or 60.
