Crystal Structure of Linoleic acid Bound in the Cyclooxygenase Channel of Prostaglandin Endoperoxide H Synthase-1.

The structure was published by Malkowski, M.G., Thuresson, E.D., Lakkides, K.M., et al., Micielli, R., Smith, W.L., and Garavito, R.M., in 2001 in a paper entitled "Structure of eicosapentaenoic and linoleic acids in the cyclooxygenase site of prostaglandin endoperoxide H synthase-1." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 Å and deposited in 2001.

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

The PDB entry contains the structure of Prostaglandin Endoperoxide H 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.
