SAE1B-1

Gene
SAE1B-1
Protein
SUMO-activating enzyme subunit 1B-1
Organism
Arabidopsis thaliana
Length
320 amino acids
Function
The dimeric enzyme acts as an E1 ligase for SUMO1 and SUMO2. It mediates ATP-dependent activation of SUMO proteins and formation of a thioester with a conserved cysteine residue on SAE2. Functionally redundant with its paralog SAE1A.
Similarity
Belongs to the ubiquitin-activating E1 family.
