Transcription Factor IIIA zinc fingers 4-6 bound to 5S rRNA 55mer (NMR structure)

The structure was published by Lee, B.M., Xu, J., Clarkson, B.K., et al., Case, D.A., Gottesfeld, J.M., and Wright, P.E., in 2006 in a paper entitled "Induced Fit and 'Lock and Key' Recognition of 5 S RNA by Zinc Fingers of Transcription Factor IIIA" (abstract).

The structure was determined using NMR spectroscopy 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 55-MER and Transcription factor IIIA.

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 heterodimers.
