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:

"
Ubiquitin activating enzymes (Uba3). Chain: B, domain 2
".

FunFam 5: Ubiquitin-activating enzyme E1-like

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 3 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.
GO Term Annotations Evidence
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).

SUMO activating enzyme activity GO:0019948
Catalysis of the activation of the proteolytically processed small ubiquitin-related modifier SUMO, through the formation of an ATP-dependent high-energy thiolester bond.
1 O42939 (/IDA)
SUMO conjugating enzyme activity GO:0061656
Isoenergetic transfer of SUMO from one protein to another via the reaction X-SUMO + Y -> Y-SUMO + X, where both the X-SUMO and Y-SUMO linkages are thioester bonds between the C-terminal amino acid of SUMO and a sulfhydryl side group of a cysteine residue.

GO Term Annotations Evidence
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

SUMO activating enzyme complex GO:0031510
A conserved heterodimeric complex with SUMO activating enzyme activity.
