Recombinant Human Aldolase B

Background

ALDOB is a liver-specific isoform of fructose-bisphosphate aldolase that primarily participates in fructose metabolism. It catalyzes the breakdown of fructose-1,6-bisphosphate and fructose-1-phosphate into dihydroxyacetone phosphate and glyceraldehyde, which are intermediates in glycolysis and gluconeogenesis. ALDOB is highly expressed in the liver, kidney, and small intestine. Mutations in ALDOB result in hereditary fructose intolerance (HFI), an autosomal recessive disorder characterized by the toxic accumulation of fructose-1-phosphate, leading to hypoglycemia, hepatomegaly, and renal dysfunction. ALDOB’s critical role in fructose metabolism highlights its importance in dietary sugar processing and maintaining energy balance.
