Specification

• Species: Human
• Source: Insect Cells
• Tag: Non
• Protein Length: 3-536;22-463 a.a.
• Description: SAE1/SAE2 is a SUMO1, 2 and 3 E1 activating enzyme and functions as a heterodimer. Cloning of the human SAE1 and SAE2 genes was first described by Desterro et al. (1999). SAE1 and SAE2 share sequence similarity to the N-terminus and C-terminus of ubiquitin E1 activating enzymes respectively (Desterro et al. 1999). SAE2 harbours the E1-like active cysteine site while SUMO1 transfer to the E2 conjugating enzyme UBE2I requires both of the SAE subunits (Desterro et al. 1999). A crystal structure of the SAE1/SAE2 dimer together with the SUMO1 adenylate has been solved at 2.45 ?ngstr?m resolution (Olsen et al. 2010).
• Form: 50 mM HEPES pH 7.5, 150 mM sodium chloride, 2 mM dithiothreitol, 10% glycerol
• Bio-activity: E1 Thioester NEDD8 Loading Assay: The activity of APP-BP1/UBA3 was validated by loading NEDD8 onto the active cysteine of APP-BP1/UBA3. Incubation of the APP-BP1/UBA3 enzyme in the presence of NEDD8 and ATP at 30?C was compared at two time points, T0 and T10 minutes. Sensitivity of the NEDD8 / APP-BP1/UBA3 thioester bond to the reducing agent DTT was confirmed.
• Molecular Mass: APP-BP1 = 60.46 kDa UBA3 = 49.35 kDa
• Purity: >98% by SDS-PAGE
• Storage: 12 months at -70°C. Avoid multiple freeze/thaw cycles.
• Concentration: 0.5 mg/ml
