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.
Moon Jellyfish live up to a year on average in an enclosed, temperature controlled system, although with immaculate care they can live up to an additional year. In the wild, the moon jellyfish lifecycle takes one year to complete.
  No, Jellyfish are pelagic organisms, this means that they live floating about in the upper layers of the open ocean, and while they can swim up and down in the water the â¦ y are carried around in the ocean by water currents. 9 people found this useful.Janelle Kerr.ellyfish live in oceans and seas all around the world, in shallow  or deep waters and in some rivers and lakes too.
