Mimosinase

In enzymology, a mimosinase (EC 3.5.1.61) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are (S)-2-amino-3-(3-hydroxy-4-oxo-4H-pyridin-1-yl)propanoate and H₂O, whereas its two products are 3-hydroxy-4H-pyrid-4-one and L-serine.

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 mimosine amidohydrolase.
