N-Acetyl-b-glucosaminylamine
N-Acetyl-b-glucosaminylamine is the product of a reaction catalyzed vy the enzyme N(4)-(beta-N-acetylglucosaminyl)-L-asparaginase [EC 3.5.1.26, Aspartylglucosaminidase, AGA]. AGA is a key enzyme in the catabolism of N-linked oligosaccharides of glycoproteins. It cleaves the asparagine from the residual N-acetylglucosamines as one of the final steps in the lysosomal breakdown of glycoproteins. Aspartylglucosaminuria (AGU) is a lysosomal disease caused by deficiency of N-aspartyl-beta-glucosaminidase. AGU is the only known lysosomal storage disease caused by an amidase deficiency. (OMIM208400).
Threonylthreonine
Threonylthreonine is a dipeptide composed of two threonine residues. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.
2-Acetamido-2-deoxy-β-D-glucosylamine
N-Acetyl-β-D-glucosamine
Beta-n-acetylglucosamine, also known as glcnac-beta or 2-acetamido-2-deoxy-D-glucose, is a member of the class of compounds known as acylaminosugars. Acylaminosugars are organic compounds containing a sugar linked to a chain through N-acyl group. Beta-n-acetylglucosamine is soluble (in water) and a very weakly acidic compound (based on its pKa). Beta-n-acetylglucosamine can be found primarily in feces and saliva. Within the cell, beta-n-acetylglucosamine is primarily located in the cytoplasm.
