Dermatan sulfate (DS) is thought to be hydrolysed from its dermatan sulfate proteoglycan (DSPG) by an unknown human beta-xylosidase. The reaction shown here is based on studies of a rabbit lysosomal enzyme fraction assay (Takagaki et al. 1988). DSPG can have many DS chains attached to it; this example shows the hydrolysis of one DS chain from DSPG.
