CC -!- FUNCTION: Activates ubiquitin by first adenylating its C-terminal
CC glycine residue with ATP, and thereafter linking this residue to the
CC side chain of a cysteine residue in E1, yielding a ubiquitin-E1
CC thioester and free AMP. {ECO:0000269|PubMed:9076989}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + ubiquitin + [E1 ubiquitin-activating enzyme]-L-cysteine
CC = AMP + diphosphate + S-ubiquitinyl-[E1 ubiquitin-activating enzyme]-
CC L-cysteine.; EC=6.2.1.45; Evidence={ECO:0000269|PubMed:9076989};
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC {ECO:0000269|PubMed:9076989}.
CC -!- SUBUNIT: Monomer. {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in leaves, flowers, roots and stems.
CC Detected in germinating seeds, cotyledons, hypocotyls, vascular
CC tissues, anthers, filaments, pollen, style, stigma, sepals, petals,
CC ovary, developing ovules, funiculi and silique walls.
CC {ECO:0000269|PubMed:9076989}.
CC -!- DEVELOPMENTAL STAGE: Expressed over the entire range of development.
CC {ECO:0000269|PubMed:9076989}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype and no changes in disease
CC susceptibility. {ECO:0000269|PubMed:17217463}.
CC -!- MISCELLANEOUS: Both UBA1 and UBA2 are able to activate ubiquitin and
CC transfer it to the E2s with equal efficiency.
CC {ECO:0000269|PubMed:9076989}.
CC -!- SIMILARITY: Belongs to the ubiquitin-activating E1 family.
CC {ECO:0000305}.
