1cqe Summary



The structure was published by Picot, D., Loll, P.J., and Garavito, R.M., in 1994 in a paper entitled "The X-ray crystal structure of the membrane protein prostaglandin H2 synthase-1." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.1 Å and deposited in 1999.

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

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