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:
"Glycosyl transferase family 29
".
FunFam 5: ST3 beta-galactoside alpha-2,3-sialyltransferase 4
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 7 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
list. The results can be filtered by typing text into the search box at the top of the table.

Catalytic activity GO:0003824
Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
