PORCINE FACTOR IXA

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

The structure was published by Brandstetter, H., Bauer, M., Huber, R., Lollar, P., and Bode, W., in 1995 in a paper entitled "X-ray structure of clotting factor IXa: active site and module structure related to Xase activity and hemophilia B." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.0 Å and deposited in 1995.

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

This PDB entry contains a complex of 2 biomacromolecules, namely FACTOR IXA.

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 heterodimers.
