Microsomal epoxide hydrolase
In enzymology, a microsomal epoxide hydrolase (mEH) (EC 3.3.2.9) is an enzyme that catalyzes the hydrolysis reaction between an epoxide and water to form a diol.

This enzyme plays a role in the uptake of bile salts within the large intestine. It functions as a Na+ dependent transporter. This enzyme participates in metabolism of xenobiotics by cytochrome p450. mEH has been identified as playing a large role in the detoxification and bioactivation of a wide variety of substrates, such as polycyclic aromatic hydrocarbons (PAHs), which are known for their carcinogenic properties.
The human homolog of microsomal epoxide hydrolase is EPHX1 and is located on chromosome 1.
