3.4.13.9 | malfunction | prolidase deficiency is a rare autosomal recessive disorder that affects the connective tissue. Symptoms of prolidase deficiency include skin lesions, mental retardation and recurrent respiratory infections. Prolidase is linked to collagen metabolism and is associated with melanoma. Prolidase is essential for collagen breakdown and the lack of this enzyme results in serious skin abnormalities. While an increase in prolidase activity and a decrease in collagen in breast cancer tissue may cause increased cancer risk. Recombinant human prolidase is used for enzyme replacement therapy | Homo sapiens |
