Biology:Mimosinase
From HandWiki
In enzymology, a mimosinase (EC 3.5.1.61) is an enzyme that catalyzes the chemical reaction
- (S)-2-amino-3-(3-hydroxy-4-oxo-4H-pyridin-1-yl)propanoate + H2O [math]\displaystyle{ \rightleftharpoons }[/math] 3-hydroxy-4H-pyrid-4-one + L-serine
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.
Occurrence
Known to occur in all Leucaena and Mimosa.[1] Negi & Borthakur 2016 clone the synthase found in L. leucocephala .[1]
Research methods
Heterologous expression in E. coli can be used.[1] Negi & Borthakur 2016 provide a protocol.[1]
