Chain A (CAS6_PSEAB | Q02MM2)

molecular function
	GO:0003723	RNA binding	Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
	GO:0004519	endonuclease activity	Catalysis of the hydrolysis of ester linkages within nucleic acids by creating internal breaks.
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
	GO:0004518	nuclease activity	Catalysis of the hydrolysis of ester linkages within nucleic acids.
biological process
	GO:0043571	maintenance of CRISPR repeat elements	Any process involved in sustaining CRISPR repeat clusters, including capture of new spacer elements, expansion or contraction of clusters, propagation of the leader sequence and repeat clusters within a genome, transfer of repeat clusters and CRISPR-associated (cas) genes to new genomes, transcription of the CRISPR repeat arrays into RNA and processing, and interaction of CRISPR/cas loci with the host genome. CRISPR (clustered regularly interspaced short palindromic repeat) elements are a family of sequence elements containing multiple direct repeats of 24-48 bp with weak dyad symmetry which are separated by regularly sized nonrepetitive spacer sequences.
	GO:0090305	nucleic acid phosphodiester bond hydrolysis	The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis.
