1fbv Summary



There is a Quite Interesting Protein Structure article for this entry.

The structure was published by Zheng, N., Wang, P., Jeffrey, P.D., and Pavletich, N.P., in 2000 in a paper entitled "Structure of a c-Cbl-UbcH7 complex: RING domain function in ubiquitin-protein ligases." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 Å and deposited in 2000.

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

This PDB entry contains a complex of 3 biomacromolecules, namely SIGNAL TRANSDUCTION PROTEIN CBL, ZAP-70 PEPTIDE, and UBIQUITIN-CONJUGATING ENZYME E12-18 KDA UBCH7.

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 heterotrimers.
