STRUCTURE OF [E271Q] LEUKOTRIENE A4 HYDROLASE

The structure was published by Rudberg, P.C., Tholander, F., Thunnissen, M.M.G.M., and Haeggstrom, J.Z., in 2002 in a paper entitled "Leukotriene A4 Hydrolase/Aminopeptidase, Glutamate 271 is a Catalyticresidue with Specific Roles in Two Distinct Enzyme Mechanisms" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2002.

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