GMPP1_ARATH | function | Essential protein during embryogenesis (PubMed:15266054). Catalyzes a reaction of the Smirnoff-Wheeler pathway, the major route to ascorbate biosynthesis in plants. Plays an essential role in plant growth and development and cell-wall architecture. Provides GDP-mannose, used for cell wall carbohydrate biosynthesis, protein N-glycosylation, as well as for the biosynthesis of the antioxidant ascorbate. |
GMPP1_ARATH | pathway | Nucleotide-sugar biosynthesis; GDP-alpha-D-mannose biosynthesis; GDP-alpha-D-mannose from alpha-D-mannose 1-phosphate (GTP route): step 1/1. |
GMPP1_ARATH | similarity | Belongs to the transferase hexapeptide repeat family. |
