Isoaspartyl peptidase/L-asparaginase

Asparaginase-like protein 1, Beta-aspartyl-peptidase, Isoaspartyl dipeptidase, L-asparagine amidohydrolase, Isoaspartyl peptidase/L-asparaginase alpha chain, Isoaspartyl peptidase/L-asparaginase beta chain.


Has both L-asparaginase and beta-aspartyl peptidase activity. May be involved in the production of L-aspartate, which can act as an excitatory neurotransmitter in some brain regions. Is highly active with L-Asp beta-methyl ester. Besides, has catalytic activity toward beta-aspartyl dipeptides and their methyl esters, including beta-L-Asp-L-Phe, beta-L-Asp-L-Phe methyl ester (aspartame), beta-L-Asp-L-Ala, beta-L-Asp-L-Leu and beta-L- Asp-L-Lys. Does not have aspartylglucosaminidase activity and is inactive toward GlcNAc-L-Asn. Likewise, has no activity toward glutamine..
