This entry represents the PAZ domain of archaeal argonaute (Ago) [1]. Ago is a DNA-guided ssDNA endonuclease that may play a role in defense against invading genetic elements that uses short ssDNA sequences as guides (gDNA) to bind complementary target strands resulting in slicing of the target DNA (tDNA) [1,2].

Argonaute (Ago) proteins are found in all three domains of life. They share a common molecular architecture, with the C-terminal lobe consisting of the middle (Mid) and PIWI (P element wimpy testis) domains and the N-terminal lobe containing the N-terminal and PIWI-Argonaute-Zwille (PAZ) domains. Archaeal argonaute proteins are guided by 5'-phosphorylated DNA strands and exclusively process cognate DNA targets. This entry represents the N-terminal domain of the archaeal argonaute protein found in M.jannaschii. This domain consists of a four stranded antiparallel beta-sheet and an alpha-helix [1].	Domain
