The Structural Basis of Aspirin Activity Inferred from the Crystal Structure of Inactivated Prostaglandin H2 Synthase

The structure was published by Loll, P.J., Picot, D., and Garavito, R.M., in 1995 in a paper entitled "The structural basis of aspirin activity inferred from the crystal structure of inactivated prostaglandin H2 synthase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.4 Å and deposited in 1995.

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

This PDB entry contains multiple copies of the structure of PROSTAGLANDIN H2 SYNTHASE-1.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.
