Metabolite Identification
Common NameGlycylproline
DescriptionGlycylproline is a dipeptide composed of glycine and proline, and is an end product of collagen metabolism that is further cleaved by prolidase (EC 3.4.13.9). The resulting proline molecules are recycled into collagen or other proteins. Prolidase deficiency is a rare autosomal recessive disease characterized by chronic ulcerative dermatitis, mental retardation, frequent infections, and massive urinary excretion of iminodipeptides. Patients with this disease have reportedly decreased prolidase enzyme activity against glycylproline (Gly-Pro). The enzyme's activity against other substrates is not as affected. Some patients with prolidase deficiency have a marked urinary excretion of glycylproline. Patients with pressure sores contain significantly more urinary glycylproline than the control (PMID: 16009141 , 7629169 , 1536787 , 10582130 ).
