2ez6 Summary


Crystal structure of Aquifex aeolicus RNase III (D44N) complexed with product of double-stranded RNA processing

The structure was published by Gan, J., Tropea, J.E., Austin, B.P., Court, D.L., Waugh, D.S., and Ji, X., in 2006 in a paper entitled "Structural Insight into the Mechanism of Double-Stranded RNA Processing by Ribonuclease III." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.05 Å and deposited in 2005.

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

This PDB entry contains a complex of 2 biomacromolecules, namely 28-MER and Ribonuclease III.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotetramers.
