1dl6 Summary



The structure was published by Chen, H.T., Legault, P., Glushka, J., Omichinski, J.G., and Scott, R.A., in 2000 in a paper entitled "Structure of a (Cys3His) zinc ribbon, a ubiquitous motif in archaeal and eucaryal transcription." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1999.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of TRANSCRIPTION FACTOR II B (TFIIB). This molecule has the UniProt identifier Q00403 (TF2B_HUMAN)search. The sample contained 58 residues which is < 90% of the natural sequence. Out of 58 residues 58 were observed and are deposited in the PDB.

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 is most likely monomeric.
