| - | '''Glycosylasparaginase''' or '''aspartylglucosaminidase''' (AGA) hydrolyzes a number of β-aspartyl amides including asparagine. AGA contains α and β subunits which derive from a precursor (PAGA) which is cleaved post-translationally. Mammalian AGA substrate is the protein-sugar bond of Asn-GlcNac. | + | '''Glycosylasparaginase''' or '''aspartylglucosaminidase''' (AGA) hydrolyzes a number of β-aspartyl amides including asparagine.
