Recombinant human FUK (fucokinase) protein is a genetically engineered enzyme critical in the metabolism of fucose, a deoxyhexose sugar involved in various biological processes. FUK catalyzes the ATP-dependent phosphorylation of L-fucose to generate L-fucose-1-phosphate, a key step in the salvage pathway of fucose metabolism. This pathway is essential for the biosynthesis of fucosylated glycoconjugates, such as glycoproteins and glycolipids, which play vital roles in cell-cell recognition, immune responses, and pathogen-host interactions. Dysregulation of fucose metabolism has been linked to developmental disorders, cancer metastasis, and immune deficiencies.
The recombinant form of human FUK is typically produced using heterologous expression systems (e.g., *E. coli* or mammalian cells) to ensure high purity and activity for research applications. Its production enables detailed structural and functional studies, including enzyme kinetics, substrate specificity, and interaction with metabolic inhibitors. Recombinant FUK also serves as a tool for investigating congenital disorders of glycosylation (CDGs) associated with fucosylation defects, such as SLC35C1 deficiency. Additionally, it supports drug discovery efforts targeting fucose-related pathways in inflammatory diseases and cancer. The availability of recombinant FUK has accelerated mechanistic insights into fucose biology while offering potential therapeutic avenues for related pathologies.
