Activating Compound | Comment | Organism | Structure |
---|---|---|---|
dithiothreitol | activates | Porphyromonas gingivalis | |
L-cysteine | activates | Porphyromonas gingivalis | |
additional information | enzyme activity and cleavage pattern are not affected by 0.1% SDS, 1% Triton X-100, or 1% octyl- and decylpyranoside | Porphyromonas gingivalis | |
Urea | 3fold activation at 6 M, probably due to unfolding of the substrate azocasein, which enhances the enzymes sensitivity for proteolytic cleavage | Porphyromonas gingivalis |
Application | Comment | Organism |
---|---|---|
molecular biology | enzyme is a convenient tool for protein chemistry due to its stability and activity under conditions of high detergent concentration used in protein solubilization and purification | Porphyromonas gingivalis |
General Stability | Organism |
---|---|
1% SDS slightly decreases enzyme activity | Porphyromonas gingivalis |
enzyme is completely inactivated in 8 M urea | Porphyromonas gingivalis |
RgpB is stable and active in buffers containing 6 M urea, 0.1% SDS, 1% Triton X-100, and 1% octyl or decylpyranoside | Porphyromonas gingivalis |
