FunFam 6: Dolichyl-phosphooligosaccharide-protein glycotrans...

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Dolichyl-phosphooligosaccharide-protein glycotransferase. [EC: 2.4.99.21]
An archaeal dolichyl phosphooligosaccharide + [protein]-L-asparagine = an archaeal dolichyl phosphate + a glycoprotein with the oligosaccharide chain attached by N-beta-D-glycosyl linkage to a protein L-asparagine.
  • The enzyme, characterized from the archaea Methanococcus voltae and Haloferax volcanii, transfers a glycan component from dolichyl phosphooligosaccharide to external proteins.
  • It is different from EC 2.4.99.18 which uses dolichyl diphosphate as carrier compound in bacteria and eukaryotes.
  • The enzyme participates in the N-glycosylation of proteins in some archaea.
  • Dolichol used by archaea is different from that used by eukaryotes; it is much shorter (C(55)-C(60)), it is alpha,omega-saturated and it may have additional unsaturated positions in the chain.
