Iduronate 2-sulfataseIduronate 2-sulfatase

Iduronate 2-sulfatase (I2S), also referred to as Alpha-L-iduronate sulfate sulfatase or Idursulfase, is a lysosomal enzyme involved in the degradation pathway of dermatan sulfate and heparan sulfate.[1]

Function

Iduronate 2-sulfatase is located in the lysosome.[1] It is involved in the lysosomal degradation pathway of dermatan sulfate and heparan sulfate.[1] I2S hydrolyzes the 2-sulfate groups of the L-iduronate 2-sulfate units of dermatan sulfate, heparan sulfate and heparin.[1] Dermatan sulfate and heparan sulfate are complex glycosaminoglycans, which are essentially large sugar molecules.[2] They play important roles in cell adhesion, growth, proliferation and repair, and their degradation and recycling in the lysosome are essential for cellular maintenance.[2]
