THE CRYSTAL STRUCTURE OF A ZINC FINGER - RNA COMPLEX REVEALS TWO MODES OF MOLECULAR RECOGNITION

The structure was published by Lu, D., Searles, M.A., and Klug, A., in 2003 in a paper entitled "Crystal Structure of a Zinc-Finger-RNA Complex Reveals Two Modes of Molecular Recognition" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.1 Å and deposited in 2003.

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

This PDB entry contains a complex of 2 biomacromolecules, namely TRANSCRIPTION FACTOR IIIA and 5S RIBOSOMAL RNA.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
