Crystal structure of RNase III mutant E110K from Aquifex aeolicus complexed with double-stranded RNA at 2.9-Angstrom Resolution

The structure was published by Gan, J., Tropea, J.E., Austin, B.P., Court, D.L., Waugh, D.S., and Ji, X., in 2005 in a paper entitled "Intermediate states of ribonuclease III in complex with double-stranded RNA" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 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 5'-R(*CP*GP*CP*GP*AP*AP*UP*UP*CP*GP*CP*G)-3' 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 heterohexamers.
