His6-NEDP1, human recombinant

Catalog number: SBB-DE0025, 50μg

NEDP1 is a protease which hydrolyzes the isopeptide bond between the C-terminus of NEDD8 and the respective lysine of the substrate protein to which the NEDD8 is covalently bound. This NEDP1 is his-tagged on the N-terminus, recombinantly expressed in E. coli.[1][2]

NEDP1 (NEDD8-specific protease 1)-is a deconjugating enzyme with specificity towards NEDDylated substrates. NEDP1 discriminates between ubiquitinated and NEDDylated targets, despite similar C-terminal regions. NEDP1 is important in regulating cullin associated ubiqutin ligase enzymes such as those of the SCF(Skp-Cullin-Fbox) family and subsequently, it’s important in regulating cell cycle progression and other biological functions. This NEDP1 is recombinantly expressed in E.coli, and contains an N-terminal His6-tag.

His6-NEDP1 Michaelis–Menten Kinetics

Figure 2. Michaelis–Menten Kinetics NEDD8 Rhodamine 110 serially diluted from 1.6 to 0.0125 uM was digested with 30pM NEDP1 over time. The assay was carried out in a reaction buffer of 50 mM HEPES pH 7.5, 1 mM TCEP, 0.1 mg/ml BSA, at 25C. Initial velocities at each substrate concentration were plotted and fit to the Michaelis–Menten equation. Kinetic parameters were calculated at: Km= 0.087 μM, Vmax = 4.44 nMs-1, kcat= 148s-1, kcat/Km= 1.70 x 109 M-1s-1.
