Aspartylglucosaminidase (AGA) gene
Gene that cause Aspartylglycosaminuria is called aspartylglucosaminidase gene, NIH Genetics Reference. It makes enzyme with the same name, aspartylglucosaminidase, or more specifically N(4)-(beta-N-acetylglucosaminyl)-L-asparaginase.
Gene Location:
The nine exons are separated by introns whose sizes in kb are shown in italics. The gene encodes a 346-amino acid single-chain polypeptide that contains a 23-amino acid signal peptide (shaded). Self-cleavage of the nascent single-chain precursor occurs between residues D205 and T206 to form the active α/β-glycosylasparaginase. Exon and intron sequences can be found in GenBank: U21273–U21281.
