Protein attributes

Sequence length	183 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Accepts the ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. Ref.3
Catalytic activity	ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine.
Pathway	Protein modification; protein ubiquitination.
Tissue specificity	Expressed in roots, petals, sepals and silique walls. Ref.2 Ref.3 Ref.8
Induction	By senescence, but not by heat shock. Ref.3 Ref.8
Sequence similarities	Belongs to the ubiquitin-conjugating enzyme family.
Sequence caution	The sequence CAA50503.1 differs from that shown. Reason: Erroneous gene model prediction.
