In enzymology a fucose-1-phosphate guanylyltransferase (EC 2.7.7.30) is an enzyme that catalyzes the chemical reactionGTP + beta-L-fucose 1-phosphate diphosphate + GDP-L-fucoseThus the two substrates of this enzyme are GTP and beta-L-fucose 1-phosphate whereas its two products are diphosphate and GDP-L-fucose.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases).
