Structural basis for 5'-end-specific recognition of the guide RNA strand by the A. fulgidus PIWI protein

The structure was published by Ma, J.B., Yuan, Y.R., Meister, G., Pei, Y., Tuschl, T., and Patel, D.J., in 2005 in a paper entitled "Structural basis for 5'-end-specific recognition of guide RNA by the A. fulgidus Piwi protein." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 2005.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely 5'-R(P*AP*GP*AP*CP*AP*G)-3', 5'-R(P*UP*GP*UP*C)-3', and hypothetical protein AF1318.
