1fkd Summary



The structure was published by Becker, J.W., Rotonda, J., McKeever, B.M., et al., Wiederrecht, G., Hermes, J.D., and Springer, J.P., in 1993 in a paper entitled "FK-506-binding protein: three-dimensional structure of the complex with the antagonist L-685,818." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.72 Å and deposited in 1992.

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

The PDB entry contains the structure of FK506 BINDING PROTEIN. This molecule has the UniProt identifier P62942 (FKB1A_HUMAN)search. The sample contained 107 residues which is 99% of the natural sequence. Out of 107 residues 107 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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
