How Proteolysis Controls Growth in a Model Bacterium (image) University of Massachusetts at Amherst Share Print E-Mail Caption UMass Amherst molecular biologists say newly idientified regulatory adaptors work in a step-wise, hierarchical way to degrade a handful of proteins. Then they recruit an additional adaptor to deliver a different set of proteins to bind even more adaptors. This may offer a new target for developing new antibiotics with a high potential to avoid triggering drug resistance.
