Protein
Polyprenol reductase 2
Gene
OsI_26070
Organism
Oryza sativa subsp. indica (Rice)
Status
Reviewed - Annotation score: 2 out of 5 - Protein inferred from homologyi

Functioni

Plays a key role in early steps of protein N-linked glycosylation by being required for the conversion of polyprenol into dolichol. Dolichols are required for the synthesis of dolichol-linked monosaccharides and the oligosaccharide precursor used for N-glycosylation. Acts as a polyprenol reductase that promotes the reduction of the alpha-isoprene unit of polyprenols into dolichols in a NADP-dependent mechanism By similarity.

Catalytic activityi

Ditrans,polycis-dolichol + NADP+ = ditrans,polycis-polyprenol + NADPH.
