Background: alpha-L-Iduronidase/IDUA

a-L-Iduronidase is a member of the glycoside hydrolase family encoded by the IDUA gene (1). It is an important enzyme required for the lysosomal degradation of glycosaminoglycans (GAGS) and hydrolyzes the non-reducing terminal a-L-iduronic acid residues in GAGS including dermatan sulfate and heparan sulfate.  Human IDUA is a 653 aa protein composed of a signal peptide removed in the lysosome for mature form and three domains: a triosephosphate isomerase barrel fold containing the catalytic site, a B-sandwich domain, and an Ig(Ig)-like domain. The protein has six reported N-glycosylation sites and the glycosylation status of the enzyme correlates with its catalytic activity (1). More than 55-disease associated missense mutations in the IDUA gene have been identified (1). Mutations in IDUA that result in enzymatic deficiency lead to the autosomal recessive disease mucopolysaccharidosis type I (MPS I) (2). MPS I can be classified as three clinical subtypes; Hurler syndrome, Hurler-Scheie syndrome, and Scheie syndrome with decreasing severity, respectively. MPS I causes progressive cellular, tissue and organ damage, and several clinical studies using enzyme replacement therapy show positive results (3,4). More recently, the IDUA gene has been linked to osteoporosis (5,6).
