Inhibitors
| EC Number | Inhibitors | Comment | Organism | Structure |
|---|---|---|---|---|
| 1.3.5.1 | additional information | residual activity: 97%. Structure of siccanin is similar to ubiquinone-1. Siccanin, is effective against enzymes from Pseudomonas aeruginosa, Pseudomonas putida, rat and mouse mitochondria but ineffective or less effective against Escherichia coli, Corynebacterium glutamicum, and porcine mitochondria enzyme. Action mode is mixed-type for quinone-dependent activity and non-competitive for succinate-dependent activity, indicating the proximity of the inhibitor-binding site to the quinone-binding site | Corynebacterium glutamicum | |
| 1.3.5.1 | additional information | residual activity: above 77%. Structure of siccanin is similar to ubiquinone-1. Siccanin, is effective against enzymes from Pseudomonas aeruginosa, Pseudomonas putida, rat and mouse mitochondria but ineffective or less effective against Escherichia coli, Corynebacterium glutamicum, and porcine mitochondria enzyme. Action mode is mixed-type for quinone-dependent activity and non-competitive for succinate-dependent activity, indicating the proximity of the inhibitor-binding site to the quinone-binding site | Escherichia coli | |

Action mode is mixed-type for quinone-dependent activity and non-competitive for succinate-dependent activity, indicating the proximity of the inhibitor-binding site to the quinone-binding site | Mus musculus | |
| 1.3.5.1 | siccanin | residual activity: 13%. Structure of siccanin is similar to ubiquinone-1. Siccanin, is effective against enzymes from Pseudomonas aeruginosa, Pseudomonas putida, rat and mouse mitochondria but ineffective or less effective against Escherichia coli, Corynebacterium glutamicum, and porcine mitochondria enzyme. Action mode is mixed-type for quinone-dependent activity and non-competitive for succinate-dependent activity, indicating the proximity of the inhibitor-binding site to the quinone-binding site | Pseudomonas aeruginosa | |
| 1.3.5.1 | siccanin | residual activity: above 1%. Structure of siccanin is similar to ubiquinone-1. Siccanin, is effective against enzymes from Pseudomonas aeruginosa, Pseudomonas putida, rat and mouse mitochondria but ineffective or less effective against Escherichia coli, Corynebacterium glutamicum, and porcine mitochondria enzyme. Action mode is mixed-type for quinone-dependent activity and non-competitive for succinate-dependent activity, indicating the proximity of the inhibitor-binding site to the quinone-binding site | Pseudomonas putida | |
| 1.3.5.1 | siccanin | residual activity: 19%. Structure of siccanin is similar to ubiquinone-1. Siccanin, is effective against enzymes from Pseudomonas aeruginosa, Pseudomonas putida, rat and mouse mitochondria but ineffective or less effective against Escherichia coli, Corynebacterium glutamicum, and porcine mitochondria enzyme. Action mode is mixed-type for quinone-dependent activity and non-competitive for succinate-dependent activity, indicating the proximity of the inhibitor-binding site to the quinone-binding site | Rattus norvegicus | |
