CATH Superfamily 3.90.550.10
Spore Coat Polysaccharide Biosynthesis Protein SpsA; Chain A
The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:
"Spore Coat Polysaccharide Biosynthesis Protein SpsA; Chain A
".
FunFam 31: Polypeptide N-acetylgalactosaminyltransferase
Please note: GO 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.
There are 2 GO terms relating to "molecular function"
The search results have been sorted with the annotations that are found most frequently at the top of the

Polypeptide N-acetylgalactosaminyltransferase activity GO:0004653
Catalysis of the reaction: UDP-N-acetyl-D-galactosamine + polypeptide = UDP + N-acetyl-D-galactosaminyl-polypeptide. This reaction is the modification of serine or threonine residues in polypeptide chains by the transfer of a N-acetylgalactose from UDP-N-acetylgalactose to the hydroxyl group of the amino acid; it is the first step in O-glycan biosynthesis.

Protein O-linked glycosylation GO:0006493
A protein glycosylation process in which a carbohydrate or carbohydrate derivative unit is added to a protein via the hydroxyl group of peptidyl-serine, peptidyl-threonine, peptidyl-hydroxylysine, or peptidyl-hydroxyproline, or via the phenol group of peptidyl-tyrosine, forming an O-glycan.

Endomembrane system GO:0012505
A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles.
