Ubiquitin is a small protein that exists in all eukaryotic cells. It performs its myriad functions through conjugation to a large range of target proteins. A variety of different modifications can occur. The ubiquitin protein itself consists of 76 amino acids and has a molecular mass of about 8.5 kDa. Activation: Ubiquitin is activated in a two-step reaction by an E1 ubiquitin-activating enzyme, which is dependent on ATP. 2  The initial step involves production of a ubiquitin-adenylate intermediate. 3  The E1 binds both ATP and ubiquitin and catalyses the acyl-adenylation of the C-terminus of the ubiqutin molecule.
