WebJan 1, 2008 · Abstract. GDP-d-mannose pyrophosphorylase (GMP) is an important enzyme in the Smirnoff–Wheeler's pathway for the biosynthesis of ascorbic acid (AsA) in plants.We have reported recently that the expression of the acerola (Malpighia glabra) GMP gene, designated MgGMP, correlates with the AsA content of the plant.The acerola plant has … WebMay 27, 2024 · GDP-l-fucose, the key substrate for fucosyloligosaccharide biosynthesis, has been synthesized via a de novo pathway in bacteria. In the present study, genes for GDP-l-fucose biosynthesis were cloned into the expression vector pET-28a (+) to construct five E. coli strains, with recombinant enzymes being purified by using Ni–NTA …
WebFeb 12, 2024 · While blocking of the biosynthesis of nucleotide sugar substrates such as GDP‐fucose leads to developmental and biochemical defects (O'Neill et al., 2001), mutation of GDP‐mannose transporters only resulted in observable phenotypes in Arabidopsis (Mortimer et al., 2013). WebTo compare the relative contribution of different GDP-fucose biosynthesis pathways into the N-glycan fucosylation, the wildtype and SLC35C1-deficient HEK293T cells were cultured in the presence of nanomolar concentrations of either radioactive fucose (salvage pathway) or radioactive mannose (de novo pathway).
