STAADIUM™ PeptiZide L-Pyr is a targeted inhibitor for pyroglutamyl-aminopeptidase-producing bacteria. The antibacterial activity of STAADIUM™ PeptiZide L-Pyr is triggered by the enzyme pyroglutamyl aminopeptidase (a.k.a. pyrase or pyrrolidonyl peptidase) that is present, not only in bacteria, but also in archaea, plants and animals. STAADIUM™ PeptiZide can be used to suppress the growth of Citrobacter freundii on diagnostic agar plates for Salmonella. L-pyrrolidonyl peptidase activity has also been exploited to distinguish Enterococcus species and Streptococcus pyogenes from other Streptococaceae species. More details in the application notes document.

Pyrasulfotole-desmethyl is a metabolite of pyrasulfotole, which is an herbicidal compound derived synthetically. It operates as a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor, effectively disrupting the biosynthesis of carotenoids. This disruption leads to a depletion in essential pigments necessary for plant growth, ultimately causing chlorosis and plant death.
