In enzymology, a theanine hydrolase (EC 3.5.1.65) is an enzyme that catalyzes the chemical reaction

N5-ethyl-L-glutamine + H2O L-glutamate + ethylamine

Thus, the two substrates of this enzyme are N5-ethyl-L-glutamine and H2O, whereas its two products are L-glutamate and ethylamine.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is N5-ethyl-L-glutamine amidohydrolase. Other names in common use include L-theanine amidohydrolase, and 5-N-ethyl-L-glutamine amidohydrolase.

Theanine, also known as L-γ-glutamylethylamide and N5-ethyl-L-glutamine, is an amino acid analogue of the proteinogenic amino acids L-glutamate and L-glutamine and is found primarily in particular plant and fungal species. It was discovered as a constituent of green tea in 1949; in 1950, it was isolated from gyokuro leaves. It constitutes about 1–2% of the dry weight of green tea leaves. Theanine provides a unique brothy or savory (umami) flavor to green tea infusions.
