Taxonomic lineage

Eukaryota › Metazoa › Nematoda › Chromadorea › Rhabditida › Rhabditoidea › Rhabditidae › Peloderinae › Caenorhabditis

Protein attributes

Sequence length	343 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	The dimeric enzyme acts as a E1 ligase for smo-1. It mediates ATP-dependent activation of smo-1 and formation of a thioester with a conserved cysteine residue on uba-2 Probable. Ref.2 Ref.3
Pathway	Protein modification; protein sumoylation.
Subunit structure	Heterodimer of aos-1 and uba-2.
Sequence similarities	Belongs to the ubiquitin-activating E1 family.
