FunFam 485: Alpha-1,3/1,6-mannosyltransferase alg-2

There are 2 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
GDP-Man:Man(1)GlcNAc(2)-PP-dolichol alpha-1,3-mannosyltransferase. [EC: 2.4.1.132]
GDP-D-mannose + D-Man-beta-(1->4)-D-GlcNAc-beta-(1->4)-D-GlcNAc- diphosphodolichol = GDP + D-Man-alpha-(1->3)-D-Man-beta-(1->4)-D-GlcNAc- beta-(1->4)-GlcNAc-diphosphodolichol.
  • The biosynthesis of asparagine-linked glycoproteins utilizes a dolichyl diphosphate-linked glycosyl donor, which is assembled by the series of membrane-bound glycosyltransferases that comprise the dolichol pathway.
  • Alg2 mannosyltransferase from Saccharomyces cerevisiae carries out an alpha-1,3-mannosylation of D-Man-beta-(1->4)-D-GlcNAc-beta-(1->4)-D- GlcNAc-diphosphodolichol, followed by an alpha-1,6-mannosylation (cf. EC 2.4.1.257), to form the first branched pentasaccharide intermediate of the dolichol pathway.

GDP-Man:Man(2)GlcNAc(2)-PP-dolichol alpha-1,6-mannosyltransferase. [EC: 2.4.1.257]
GDP-D-mannose + D-Man-alpha-(1->3)-D-Man-beta-(1->4)-D-GlcNAc-beta- (1->4)-D-GlcNAc-diphosphodolichol = GDP + D-Man-alpha-(1->3)-(D-Man- alpha-(1->6))-D-Man-beta-(1->4)-D-GlcNAc-beta-(1->4)-D-GlcNAc- diphosphodolichol.
  • The biosynthesis of asparagine-linked glycoproteins utilizes a dolichyl diphosphate-linked glycosyl donor, which is assembled by the series of membrane-bound glycosyltransferases that comprise the dolichol pathway.
