According to the series of assays performed by Cleland (1967), the linear rate of pyruvate formation at various concentrations of inhibitors demonstrated that L-cysteine and D-serine competitively inhibit the enzyme SDH. The reason that SDH activity is inhibited by L-cysteine is because an inorganic sulfur is created from L-Cysteine via Cystine Desulfrase and sulfur-containing groups are known to promote inhibition. L-threonine competitively inhibits Serine Dehydratase a… WebAug 30, 2024 · The uridyl peptide antibiotics (UPAs), of which pacidamycin is a member, have a clinically unexploited mode of action and an unusual assembly. Perhaps the most striking feature of these molecules is the biosynthetically unique 3′‐deoxyuridine that they share. This moiety is generated by an unusual, small and monomeric dehydratase, …
