2nuf Summary


Crystal structure of RNase III from Aquifex aeolicus complexed with ds-RNA at 2.5-Angstrom Resolution

The structure was published by Gan, J., Shaw, G., Tropea, J.E., Waugh, D.S., Court, D.L., and Ji, X., in 2007 in a paper entitled "A stepwise model for double-stranded RNA processing by ribonuclease III." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 2006.

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.
