X-RAY CRYSTAL STRUCTURE OF HUMAN CERULOPLASMIN AT 3.0 ANGSTROMS

The structure was published by Zaitseva, I., Zaitsev, V., Card, G., et al., Bax, B., Ralph, A., and Lindley, P., in 1996 in a paper entitled "The X-ray structure of human serum ceruloplasmin at 3.1 angstrom: Nature of the copper centres." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.0 Å and deposited in 1996.

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

The PDB entry contains the structure of CERULOPLASMIN. This molecule has the UniProt identifier P00450 (CERU_HUMAN)search. The sample contained 1046 residues which is 100% of the natural sequence. Out of 1046 residues 1010 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.
