生化/生理作用
L-Aspartic acid β-(7-amido-4-methylcoumarin) is used as a fluorogenic substrate for studying the specificity and kinetics of lysosomal glycoasparaginase(s) (aspartylglucosaminidase) and L-asparaginase(s).
L-Aspartic acid-β-7-amido-4-methylcoumarin is sensitive and specific fluorogenic substrate used to assay for lysosomal glycoasparaginase (aspartylglucosaminidase) activity and the diagnosis of aspartylglucosaminuria.

Serum, plasma, and lymphocytes from aspartylglycosaminuria (AGU) patients and carriers and from normal controls were incubated with a fluorescent glycosylasparaginase substrate, L-aspartic acid beta-(7-amido-4-methylcoumarin), and the release of 7-amino-4-methylcoumarin was measured fluorometrically after incubation for 1-4 h. The mean glycosylasparaginase

L-Aspartic acid-beta-7-amido-4-methylcoumarin is a sensitive and specific fluorogenic substrate for lysosomal glycoasparaginase (aspartylglucosaminidase). Fibroblasts and leukocytes from 8 patients with aspartylglucosaminuria, showed 1-7% of the mean normal glycoasparaginase activity. Heterozygotes showed intermediate activities. Glycoasparaginase activity in chorionic villi, cultured trophoblasts

The antineoplastic enzyme L-asparaginase is commonly used for the induction of remission in acute lymphoblastic leukemia (ALL). There is no simple method available for measuring the activity of this highly toxic drug. We incubated L-asparaginase from Erwinia chrysanthemi with L-aspartic

Analytical biochemistry, 208(2), 372-374 (1993-02-01)
Recent experimental work on the mechanism of action of glycosylasparaginase suggests that the enzyme specifically reacts toward the L-asparagine or L-aspartic acid moiety of its substrates. Based on this, a new sensitive assay for glycosylasparaginase activity has been developed using

Biochemical and biophysical research communications, 377(4), 1168-1172 (2008-11-11)
To elucidate the basis of aspartylglucosaminuria (AGU) from the viewpoint of enzyme structure, we constructed structural models of mutant aspartylglucosaminidase (AGA) proteins using molecular modeling software, TINKER. We classified the amino acid substitutions responsible for AGU and divided them into
