Metabolite Identification
Common Name3-Aminoisobutanoic acid
Description3-Aminoisobutyrate, also known as 2-methyl-b-alanine or baib, belongs to the class of organic compounds known as beta amino acids and derivatives. These are amino acids having a (-NH2) group attached to the beta carbon atom. 3-Aminoisobutyrate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 3-Aminoisobutyrate exists in all eukaryotes, ranging from yeast to humans. 3-Aminoisobutyrate is a potentially toxic compound.

Specific function:
Catalyzes the hydrolysis of the amide bond in N-(4-oxoglutarate)-L-cysteinylglycine (deaminated glutathione), a metabolite repair reaction to dispose of the harmful deaminated glutathione. Plays a role in cell growth and apoptosis. Has tumor suppressor properties that enhances the apoptotic responsiveness in cancer cells. It is also a negative regulator of primary T-cells.
