ATOMIC STRUCTURE OF FKBP-FK506, AN IMMUNOPHILIN-IMMUNOSUPPRESSANT COMPLEX

The structure was published by Van Duyne, G.D., Standaert, R.F., Karplus, P.A., Schreiber, S.L., and Clardy, J., in 1991 in a paper entitled "Atomic structure of FKBP-FK506, an immunophilin-immunosuppressant complex." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 1991.

The experimental data on which the structure is based was not 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 most likely forms homodimers.
