In Type I and III CRISPR/Cas systems, the Cas6 family of endoribonucleases generates functional CRISPR-derived RNAs by site-specific cleavage of repeat sequences in precursor transcripts. The structure of Cas6 [1] showed it adopts a tandem ferredoxin/RRM fold. This entry represents the N-terminal domain.	Domain
