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.
Jellyfish do have symbiotic relationships. For example, some fish are immune to the sting of a jellyfish, so they can take shelter among the jellyfishâs tentacles, thereby baiting trap for other fish.In return, the fish get to share the meal with the jellyfish.In its juvenile stage the spider crab can be seen inside the bell of the jellyfish.owever, some live in depths of over 12,000 feet.
