Abstract
The catabolism of glycosaminoglycans begins with endohydrolysis of polysaccharides to oligosaccharides followed by the sequential action of an array of exoenzymes to reduce these oligosaccharides to monosaccharides and inorganic sulfate. In a lysosomal storage disorder known as mucopolysaccharidosis I, caused by a deficiency of the exohydrolase alpha-l-iduronidase, fragments of two different glycosaminoglycans, dermatan sulfate and heparan sulfate, have been shown to accumulate. Oligosaccharides isolated from the urine of a mucopolysaccharidosis I patient using anion exchange and gel filtration chromatography were identified as di-, tri-, tetra-, penta-, and hexasaccharides using electrospra..
