3tzi Summary


X-ray crystal structure of arachidonic acid bound in the cyclooxygenase channel of G533V murine COX-2

The structure was published by Vecchio, A.J., Orlando, B.J., Nandagiri, R., and Malkowski, M.G., in 2012 in a paper entitled "Investigating Substrate Promiscuity in Cyclooxygenase-2: THE ROLE OF ARG-120 AND RESIDUES LINING THE HYDROPHOBIC GROOVE." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.15 Å and deposited in 2011.

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.
