Discovery
The sEH was first identified in the cytosolic fraction of mouse liver through its activity on epoxide containing substrates such as juvenile hormone and lipid epoxides such as epoxystearate. The soluble EH activity was shown to be distinct from that of the microsomal epoxide hydrolase (mEH) previously discovered with a different substrate selectivity and cellular localization than the mEH. Studies using a lipid epoxide as a substrate detected this activity in the soluble fraction of multiple organs, though at a lesser amount than in liver and kidney. The enzyme activity was detected in rabbits, mice and rats, and humans, and it is now believed to be ubiquitous in vertebrates. The proposed enzyme was first named cytosolic epoxide hydrolase; however, after its discovery inside the peroxisomes of some organs, it was renamed soluble epoxide hydrolase or sEH.

Famous quotes containing the word discovery:
“Your discovery of the contradiction caused me the greatest surprise and, I would almost say, consternation, since it has shaken the basis on which I intended to build my arithmetic.... It is all the more serious since, with the loss of my rule V, not only the foundations of my arithmetic, but also the sole possible foundations of arithmetic seem to vanish.”
—Gottlob Frege (1848–1925)
“The new supplants the old. Yet men’s minds are stuffed with outworn bunk. Educating the young in the latest findings of authorities and scholars in the social sciences is important. It is equally important to devise ways and means for aiding the middle-aged and old to reexamine hang-over unscientific doctrines and ideas in the light of recent discovery and research.”
—Mary Barnett Gilson (1877–?)
“That the discovery of this great truth, which lies so near and obvious to the mind, should be attained to by the reason of so very few, is a sad instance of the stupidity and inattention of men, who, though they are surrounded with such clear manifestations of the Deity, are yet so little affected by them, that they seem as it were blinded with excess of light.”
—George Berkeley (1685–1753)
