Recombinant human XYLB protein, derived from the xylulokinase (XYLB) gene located on chromosome 3. plays a critical role in carbohydrate metabolism. Xylulokinase is a key enzyme in the pentose phosphate pathway, catalyzing the ATP-dependent phosphorylation of D-xylulose to xylulose-5-phosphate. This reaction bridges glycolysis with nucleotide biosynthesis and redox balance regulation. Dysregulation of XYLB has been implicated in metabolic disorders, including diabetes, due to its influence on glucose homeostasis and insulin signaling pathways.
Produced via genetic engineering, recombinant XYLB is typically expressed in prokaryotic (e.g., E. coli) or eukaryotic systems (e.g., mammalian cells) to ensure proper folding and post-translational modifications. Its purification often involves affinity chromatography tags like His-tag for high-yield recovery. Researchers employ this recombinant protein to study enzymatic kinetics, substrate specificity, and structural features through X-ray crystallography or cryo-EM. It also serves as a tool for investigating metabolic disease mechanisms and screening potential therapeutic compounds targeting carbohydrate metabolism. Recent studies explore its diagnostic potential as a biomarker for metabolic syndrome. The development of active recombinant XYLB has accelerated research into rare genetic diseases linked to xylulokinase deficiencies while providing insights into broader metabolic network regulation.
