Human activated protein C

The structure was published by Mather, T., Oganessyan, V., Hof, P., et al., Foundling, S., Esmon, C., and Bode, W., in 1996 in a paper entitled "The 2.8 A crystal structure of Gla-domainless activated protein C." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 1996.

A re-refinement of this structure, using the same experimental data but carried out by different authors, is available as entry 3f6u.

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

This PDB entry contains a complex of 2 biomacromolecules, namely ACTIVATED PROTEIN C.

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.
