Protein Classification

saposin domain-containing protein; MgtC/SapB family protein( domain architecture ID 12191173)

saposin domain-containing protein such as saposins, which are accessory proteins that aid in the degradation of sphingolipids by hydrolytic enzymes| uncharacterized MgtC/SapB family protein containing a DUF4010 domain; with similarity in its N-terminus to Brucella MgtC, a virulence factor required for growth in low Mg(2+) medium and for intramacrophage survival, and to Bacillus subtilis SapB

315-388 3.33e-20

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.

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.
