We report the cloning and expression of a cDNA that encodes a soluble epoxide hydrolase from human liver. The 2101-base clone predicts a 554-residue protein (Mr 62,640) with an apparently imperfect peroxisomal targeting signal of Ser-Lys-Met at the carboxy terminus. The cDNA was expressed in the baculovirus system in the Spodoptera frugiperda 21 cell line. The recombinant protein was similar to soluble epoxide hydrolase isolated from human liver in terms of molecular weight, hydrolytic activity, inhibition, and immunoreactivity.
