HUMAN PSORIASIN (S100A7) CA2+ BOUND FORM (CRYSTAL FORM I)

The structure was published by Brodersen, D.E., Nyborg, J., and Kjeldgaard, M., in 1999 in a paper entitled "Zinc-binding site of an S100 protein revealed. Two crystal structures of Ca2+-bound human psoriasin (S100A7) in the Zn2+-loaded and Zn2+-free states." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 1998.

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

This PDB entry contains multiple copies of the structure of PSORIASIN.

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.
