Ubiquitin is a small (8.5 kDa) regulatory protein that has been found in almost all tissues (ubiquitously) of eukaryotic organisms.It was discovered in 1975 by Gideon Goldstein and further characterized throughout the 1970s and 1980s. 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.

Answers. Best Answer: It really depends on the location of you and the package. You know that in some areas the weather is terrible and people are without power etc... But in normal situations if the seller shipped to you priority mail 3-5 days is usually pretty precise.If it was shipped 1st class mail it may take anywhere from 2-9 days. But being your not to far away I would think you should have it by no later than Monday.I sell on Ebay and some of my customers receive their packages in 2 days but some 5 days. I do ship using UPS Priority Mail.how more ok, so i bought a GH3 on ebay and the seller sent it though UPS. it was shipped out on the 4th and now it is the 5th of febuary. and one other thing... the package was shipped out like 140-150 miles away form me.
