peptide-N4-(N-acetyl-beta-glucosaminyl)asparagine amidase activity

Definition

Target type: molecularfunction

Catalysis of the reaction: 4-N-(N-acetyl-D-glucosaminyl)-protein + H2O = N-acetyl-beta-D-glucosaminylamine + peptide L-aspartate. This reaction is the hydrolysis of an N4-(acetyl-beta-D-glucosaminyl)asparagine residue in which the N-acetyl-D-glucosamine residue may be further glycosylated, to yield a (substituted) N-acetyl-beta-D-glucosaminylamine and the peptide containing an aspartic residue. [EC:3.5.1.52]

Peptide-N4-(N-acetyl-beta-glucosaminyl)asparagine amidase activity refers to the catalytic ability of an enzyme to cleave the N-glycosidic bond between the asparagine residue of a protein and the N-acetylglucosamine moiety of an N-linked glycan. This process is essential for the maturation and proper folding of glycoproteins. The enzyme specifically recognizes and hydrolyzes the linkage between the amide group of asparagine and the N-acetylglucosamine sugar, releasing the glycan from the protein. This activity is crucial for various cellular processes, including protein trafficking, signaling, and cell-cell interactions.'

dactinomycinDactinomycin: A compound composed of a two CYCLIC PEPTIDES attached to a phenoxazine that is derived from STREPTOMYCES parvullus. It binds to DNA and inhibits RNA synthesis (transcription), with chain elongation more sensitive than initiation, termination, or release. As a result of impaired mRNA production, protein synthesis also declines after dactinomycin therapy. (From AMA Drug Evaluations Annual, 1993, p2015)actinomycinmutagen
