Figure 1: Signal to Background: The signal to background ratio was determined by 100% hydrolysis of either 50nM or 500nM Ubiquitin-Rhodamine 110 to liberate the quenched conjugate. Assay Buffer: 50mM HEPES pH7.5, 100mM NaCl, 1mM TCEP, 0.1mg/ml BSA.
Figure 2: Robustness of Rhodamine 110 vs. 7-amino-4- methylcoumarin (AMC) substrates: Fluorescent substrates (500nM Ub-Rh110/Ub-AMC) were incubated +/- 5pM UcHL3 in a 384 well plate (n=16), and progress curves were normalized to the maximum fluorescence signal to produce “% reaction progress”. The Z’ value was calculated at each time-point.

Description
Ubiquitin is a 76 amino acid post-translational modifier expressed throughout all tissues in eukaryotic organisms. The many roles of ubiquitin modification include proteasomal degradation, signal transduction, inflammatory response and DNA damage repair. Ubiquitin modification occurs through a pyramidal cascade of an E1 activating enzyme, E2 conjugating enzymes and an E3 ubiquitin ligase. This enzymatic cascade results in modification of a ε-amine of a lysine residue on a substrate protein. Substrates may either be mono- or poly-ubiquitinated by M1, K6, 11, 27, 29, 33, 48 or 63 linkages. Removal of ubiquitin from a substrate protein occurs via deconjugating enzymes, of which there are nearly 100 known enzymes with various specificities.
