Structure of a CRISPR associated protein Cas2 from Desulfovibrio vulgaris

Template:ABSTRACT PUBMED 21139194

Function

[Q72WF4_DESVH] CRISPR (clustered regularly interspaced short palindromic repeat), is an adaptive immune system that provides protection against mobile genetic elements (viruses, transposable elements and conjugative plasmids). CRISPR clusters contain sequences complementary to antecedent mobile elements and target invading nucleic acids. CRISPR clusters are transcribed and processed into CRISPR RNA (crRNA). Functions as a ssRNA-specific endoribonuclease (By similarity).[HAMAP-Rule:MF_01471]
