Crystal Strcture of Human Prolidase

Structural highlights

2okn is a 2 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:	MN, PI
Related:	2iw2
Gene:	PEPD, PRD (Homo sapiens)
Activity:	Xaa-Pro dipeptidase, with EC number 3.4.13.9
Resources:	FirstGlance, OCA, RCSB, PDBsum

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.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
