General annotation (Comments)

Function

Adds the second glucose residue to the lipid-linked oligosaccharide precursor for N-linked glycosylation. Transfers glucose from dolichyl phosphate glucose (Dol-P-Glc) onto the lipid-linked oligosaccharide Glc1Man9GlcNAc(2)-PP-Dol By similarity.

Catalytic activity

Dolichyl beta-D-glucosyl phosphate + D-Glc-alpha-(1->3)-D-Man-alpha-(1->2)-D-Man-alpha-(1->2)-D-Man-alpha-(1->3)-[D-Man-alpha-(1->2)-D-Man-alpha-(1->3)-(D-Man-alpha-(1->2)-D-Man-alpha-(1->6))-D-Man-alpha-(1->6)]-D-Man-beta-(1->4)-D-GlcNAc-beta-(1->4)-D-GlcNAc-diphosphodolichol = D-Glc-alpha-(1->3)-D-Glc-alpha-(1->3)-D-Man-alpha-(1->2)-D-Man-alpha-(1->2)-D-Man-alpha-(1->3)-[D-Man-alpha-(1->2)-D-Man-alpha-(1->3)-(D-Man-alpha-(1->2)-D-Man-alpha-(1->6))-D-Man-alpha-(1->6)]-D-Man-beta-(1->4)-D-GlcNAc-beta-(1->4)-D-GlcNAc-diphosphodolichol + dolichyl phosphate.

Pathway

Protein modification; protein glycosylation.

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.

Sequence similarities

Belongs to the ALG6/ALG8 glucosyltransferase family.

Sequence caution

The sequence AAC27468.1 differs from that shown. Reason: Erroneous gene model prediction.
