Functional Families

Overview of the Structural Clusters (SC) and Functional Families within this CATH Superfamily. Clusters with a representative structure are represented by a filled circle.

Superfamily EC Annotations

Note: the EC figure is not being displayed for this superfamily as there are more than 100 different EC terms.

There are 3 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Acyloxyacyl hydrolase. [EC: 3.1.1.77]
3-(acyloxy)acyl group of bacterial toxin = 3-hydroxyacyl group of bacterial toxin + a fatty acid.
  • The substrate is lipid A on the reducing end of the toxic lipopolysaccharide (LPS) of Salmonella typhimurium and related organisms.
  • It consists of diglucosamine, beta-D-GlcN-(1->6)-D-GlcN, attached by glycosylation on O-6 of its non-reducing residue, phosphorylated on O-4 of this residue and on O-1 of its potentially reducing residue.
  • Both residues carry 3-(acyloxy)acyl groups on N-2 and O-3.
  • The enzyme from human leukocytes detoxifies the lipid by hydrolyzing the secondary acyl groups from O-3 of the 3-hydroxyacyl groups on the disaccharide (LPS).
  • It also possesses a wide range of phospholipase and acyltransferase activities (e.g. EC 3.1.1.4, EC 3.1.1.5, EC 3.1.1.32 and EC 3.1.1.52), hydrolyzing diacylglycerol and phosphatidyl compounds, but not triacylglycerols.
  • It has a preference for saturated C(12)-C(16) acyl groups.

Phytepsin. [EC: 3.4.23.40]
Prefers hydrophobic residues Phe, Val, Ile, Leu, and Ala at P1 and P1', but also cleaves -Phe-|-Asp- and -Asp-|-Asp- bonds in 2S albumin from plant seeds.
  • Known particularly fron barley grain, but present in other plants also.
  • Belongs to peptidase family A1.
 2 A0A287GN26 P42210
Sphingomyelin phosphodiesterase. [EC: 3.1.4.12]
Sphingomyelin + H(2)O = N-acylsphingosine + phosphocholine.
  • Has very little activity on phosphatidylcholine.
