Saposin (B) Domains; Present in multiple copies in prosaposin and in pulmonary surfactant-associated protein B. In plant aspartic proteinases, a saposin domain is circularly permuted. This causes the prediction algorithm to predict two such domains, where only one is truly present.

318-353 1.04e-08

Saposin-like type B, region 1; Saposin B is a small non-enzymatic glycoprotein required for the breakdown of cerebroside sulphates (sulphatides) in lysosomes. Saposin B contains three intramolecular disulphide bridges, exists as a dimer and is remarkably heat, protease, and pH stable. The crystal structure of human saposin B reveals an unusual shell-like dimer consisting of a monolayer of alpha-helices enclosing a large hydrophobic cavity. It is one of the most studied members of the saposin protein family and it is involved in the hydrolysis of glycolipids and glycerolipids. SapB is unique in the saposin family in that it facilitates degradation by interacting with the substrate, not the enzymes.

Saposin (B) Domains; Present in multiple copies in prosaposin and in pulmonary surfactant-associated protein B. In plant aspartic proteinases, a saposin domain is circularly permuted. This causes the prediction algorithm to predict two such domains, where only one is truly present.

Saposin-like type B, region 1; Saposin B is a small non-enzymatic glycoprotein required for the breakdown of cerebroside sulphates (sulphatides) in lysosomes. Saposin B contains three intramolecular disulphide bridges, exists as a dimer and is remarkably heat, protease, and pH stable. The crystal structure of human saposin B reveals an unusual shell-like dimer consisting of a monolayer of alpha-helices enclosing a large hydrophobic cavity. It is one of the most studied members of the saposin protein family and it is involved in the hydrolysis of glycolipids and glycerolipids. SapB is unique in the saposin family in that it facilitates degradation by interacting with the substrate, not the enzymes.
