Crystal structure of full length Argonaute from Pyrococcus furiosus

Structural highlights

1u04 is a 1 chain structure with sequence from Pyrfu. The February 2008 RCSB PDB Molecule of the Month feature on Small Interfering RNA by David S. Goodsell is 10.2210/rcsb_pdb/mom_2008_2. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Publication Abstract from PubMed

Argonaute proteins and small interfering RNAs (siRNAs) are the known signature components of the RNA interference effector complex RNA-induced silencing complex (RISC). However, the identity of "Slicer," the enzyme that cleaves the messenger RNA (mRNA) as directed by the siRNA, has not been resolved. Here, we report the crystal structure of the Argonaute protein from Pyrococcus furiosus at 2.25 angstrom resolution. The structure reveals a crescent-shaped base made up of the amino-terminal, middle, and PIWI domains. The Piwi Argonaute Zwille (PAZ) domain is held above the base by a "stalk"-like region. The PIWI domain (named for the protein piwi) is similar to ribonuclease H, with a conserved active site aspartate-aspartate-glutamate motif, strongly implicating Argonaute as "Slicer." The architecture of the molecule and the placement of the PAZ and PIWI domains define a groove for substrate binding and suggest a mechanism for siRNA-guided mRNA cleavage.
