[https://www.uniprot.org/uniprot/ASPG_ELIMR ASPG_ELIMR] Cleaves the GlcNAc-Asn bond which joins oligosaccharides to the peptide of asparagine-linked glycoproteins. Requires that the glycosylated asparagine moiety is not substituted on its N-(R1) and C- (R2) terminus.

== Publication Abstract from PubMed ==
 +
A variety of proteins, including glycosylasparaginase, have recently been found to activate functions by self-catalyzed peptide bond rearrangements from single-chain precursors. Here we present the 1.9 A crystal structures of glycosylasparaginase precursors that are able to autoproteolyze via an N --&gt; O acyl shift. Several conserved residues are aligned around the scissile peptide bond that is in a highly strained trans peptide bond configuration. The structure illustrates how a nucleophilic side chain may attack the scissile peptide bond at the immediate upstream backbone carbonyl and provides an understanding of the structural basis for peptide bond cleavage via an N --&gt; O or N --&gt; S acyl shift that is used by various groups of intramolecular autoprocessing proteins.
