Ubiquitin activating enzyme E1 is responsible for the first step in ubiquitin-protein isopeptide bond formation and is a critical component for the initiation of in vitro conjugation reactions. E1 activates ubiquitin by first adenylating with ATP the C-terminal glycine carboxyl group of ubiquitin and, thereafter, linking this residue to the sulphydryl side chain moiety of a cysteine residue in E1 by forming a high energy thiol ester bond and liberating free AMP. There are two active sites within the E1 molecule allowing it to accommodate two ubiquitin molecules at one time, with a new ubiquitin forming an adenylate intermediate as the previous one is transferred to the thiol site. The activated ubiquitin is then transferred to the lysine of target proteins via the E2/E3 conjugation cascade.


Product Details

MW:118 kDa

Source:Produced in E. coli BL21 (λDE3) expression system and containing a C-terminal His6-tag. Full length human ubiquitin-activating enzyme E1.

UniProt ID:P22314

Formulation:Liquid. In 50mM TRIS-HCl, pH 7.5, containing 1.0mM DTT.

Purity:≥90% (SDS-PAGE)

Purity Detail:Purified by multi-step chromatography.

Shipping:Shipped on Dry Ice

Long Term Storage:-80°C

Handling:Avoid freeze/thaw cycles.

Scientific Background:Results demonstrate the formation of ubiquitin thioester linked E2 conjugates of the expected size in all TE +ve control reactions. The absence of such conjugates in TE –ve control reactions demonstrates that their formation is ATP dependent (required for E1 activation) and hence derived from the ubiquitin cascade.

Regulatory Status:RUO - Research Use Only
