Active Recombinant Human SAE1/UBA2, GST/His-tagged

• Cat.No.: SAE1-170H
• Product Overview: Recombinant human SAE1 (amino acid residues 1-346), fused with N-terminal GST, Human UBA2 (amino acid residues 1-640), fused with N-terminal His, was expressed in E.coli.

Specification

• Species: Human
• Source: E.coli
• Tag: GST&His
• Protein Length: 1-346 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).
• Form: 50 mM HEPES pH 7.5, 150 mM sodium chloride, 2 mM dithiothreitol, 10% glycerol
• Bio-activity: E1 Thioester SUMO Loading Assay: The activity of GST-SAE1/His-SAE2 was validated by loading SUMO1 onto the active cysteine of GST-SAE1/His-SAE2. Incubation of the GST-SAE1/His-SAE2 enzyme in the presence of SUMO1 and ATP at 30?C was compared at two time points, T0 and T10 minutes. Sensitivity of the SUMO / GST-SAE1/His-SAE2 thioester bond to the reducing agent DTT was confirmed.
• Molecular Mass: SAE1 = 64.8 kDa SAE2 = 73.4 kDa
• Purity: >98% by SDS-PAGE
• Storage: 12 months at -70°C. Avoid multiple freeze/thaw cycles.
• Concentration: 0.5 mg/ml
