X-ray crystal structure of 1-arachidonoyl glycerol bound to the cyclooxygenase channel of cyclooxygenase-2

The structure was published by Vecchio, A.J. and Malkowski, M.G., in 2011 in a paper entitled "The structural basis of endocannabinoid oxygenation by cyclooxygenase-2." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2010.

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

This PDB entry contains multiple copies of the structure of Prostaglandin G/H synthase 2.

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.
