Activating Compound

Activating Compound Comment Organism Structure
Bmh1p a yeast homologue of the human FAS, acts as an activating ExoS cofactor, overview Pseudomonas aeruginosa

Application

Application Comment Organism
drug development the enzyme can be a target for anti-bacterial treatment Pseudomonas aeruginosa

Inhibitors

Inhibitors Comment Organism Structure
0469-0796 restores yeast growth after treatment with ExoS Pseudomonas aeruginosa
4296-1011 restores yeast growth after treatment with ExoS Pseudomonas aeruginosa
diosmin restores yeast growth after treatment with ExoS Pseudomonas aeruginosa
E216-5303 restores yeast growth after treatment with ExoS Pseudomonas aeruginosa
everninic acid restores yeast growth after treatment with ExoS Pseudomonas aeruginosa
exosin a small molecule inhibitor, that modulates ExoS ADP-ribosyltransferase activity in vitro, suggesting the inhibition is direct. Exosin and two of its analogues display a significant protective effect against Pseudomonas infection in vivo, competitive against NAD+ Pseudomonas aeruginosa
flavokawain B restores yeast growth after treatment with ExoS Pseudomonas aeruginosa
