UBA3, also known as NEDD8-activating enzyme E1 catalytic subunit, is the catalytic subunit of the dimeric UBA3-NAE1 E1 enzyme. E1 activates NEDD8 by first adenylating its C-terminal glycine residue with ATP, thereafter linking this residue to the side chain of the catalytic cysteine, yielding a NEDD8-UBA3 thioester and free AMP. E1 finally transfers NEDD8 to the catalytic cysteine of UBE2M.
Source:Recombinant corresponding to aa1-463 from human UBA3, fused to His-tag at N-terminus, expressed in E.coli.
Enzyme Activity:Not determined. This product is recommended for use in applications that do not require a catalytically active form of the protein.
