Protein

Fucose-1-phosphate guanylyltransferase

Gene

FPGT

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the formation of GDP-L-fucose from GTP and L-fucose-1-phosphate. Functions as a salvage pathway to reutilize L-fucose arising from the turnover of glycoproteins and glycolipids.

Caution

Catalytic activityi

GTP + beta-L-fucose 1-phosphate = diphosphate + GDP-L-fucose.
