Crystal Strcture of Human Prolidase

Disease

[PEPD_HUMAN] Defects in PEPD are a cause of prolidase deficiency (PD) [MIM:170100]. Prolidase deficiency is an autosomal recessive disorder associated with iminodipeptiduria. The clinical phenotype includes skin ulcers, mental retardation, recurrent infections, and a characteristic facies. These features, however are incompletely penetrant and highly variable in both age of onset and severity. There is a tight linkage between the polymorphisms of prolidase and the myotonic dystrophy trait.[1][2][3][4]

Function

[PEPD_HUMAN] Splits dipeptides with a prolyl or hydroxyprolyl residue in the C-terminal position. Plays an important role in collagen metabolism because the high level of iminoacids in collagen.

About this Structure

2okn is a 2 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
