Function
[A0A0D6FWC1_SALTM] The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate.[HAMAP-Rule:MF_00131][SAAS:SAAS01111173]
Publication Abstract from PubMed
Light-regulation of drug molecules has gained growing interest in the fields of biochemical and pharmacological research in recent years. In addition, a serious need for novel molecular targets of antibiotics has emerged presently. Here, we present the development of a photo-controllable, azobenzene-based antibiotic precursor towards tryptophan synthase (TS), an essential metabolic multienzyme complex in bacteria. The compound exhibited a medium-strong inhibition of TS in its E configuration, and a 5-fold lower inhibition strength in its Z configuration. Using a combination of biochemical, crystallographic, and computational analyses we characterized the inhibition mode of this compound. Remarkably, binding of the inhibitor to a hitherto not considered cavity causes an unproductive conformation of TS leading to non-competitive inhibition of tryptophan production. In conclusion, we created a promising lead compound for the combat of bacterial diseases, which targets an essential metabolic enzyme, and whose inhibition strength can be controlled with light.
