WebFeb 28, 2024 · The de novo synthesis involves the formation of UDP-glucose, which is epimerized to UDP-galactose by the activity of UDP-glucose-4-epimerase ( Seifert et al., 2002 ). Beside the de novo pathway, which always leads to nucleotide sugars, most organisms have developed a recycling pathway for galactose.

WebThe autosomal dominant form is caused by a mutation inSTAT3, and the autosomal recessive form by mutations in DOCK8 and rarely in tyrosine kinase 2 (TYK2) or phosphoglucomutase 3 (PGM3). The autosomal recessive forms of HIES are clinically somewhat different and are described separately. Phosphoglucomutase (EC 5.4.2.2) is an enzyme that transfers a phosphate group on an α-D-glucose monomer from the 1 to the 6 position in the forward direction or the 6 to the 1 position in the reverse direction. More precisely, it facilitates the interconversion of glucose 1-phosphate and glucose 6-phosphate.
