FunFam 32: Phosphatidylinositol-glycan-specific phospholipase...

There are 1 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
Glycosylphosphatidylinositol phospholipase D. [EC: 3.1.4.50]
6-(alpha-D-glucosaminyl)-1-phosphatidyl-1D-myo-inositol + H(2)O = 6-(alpha-D-glucosaminyl)-1D-myo-inositol + phosphatidate.
  • This enzyme is also active when O-4 of the glucosamine is substituted by carrying the oligosaccharide that can link a protein to the structure.
  • It therefore cleaves proteins from the lipid part of the glycosylphosphatidylinositol (GPI) anchors, but does so by hydrolysis, whereas EC 4.6.1.14 does so by elimination.
  • It acts on plasma membranes only after solubilization of the substrate with detergents or solvents, but it may act on intracellular membranes.
