1EK1, 1EK2 - PubMed Abstract: 
The structures of two alkylurea inhibitors complexed with murine soluble epoxide hydrolase have been determined by x-ray crystallographic methods. The alkyl substituents of each inhibitor make extensive hydrophobic contacts in the soluble epoxide hydrolase active site, and each urea carbonyl oxygen accepts hydrogen bonds from the phenolic hydroxyl groups of Tyr(381) and Tyr(465) ...
