N-terminal methionine excision (NME) is the major proteolytic pathway responsible for the diversity of N-terminal amino acids in proteins. Dedicated NME components have been identified in all organisms, in all compartments in which protein synthesis occurs: cytoplasm, plastids and mitochondria. Recent studies have revealed that NME is regulated at various(More)
For several decades, molecular recognition has been considered one of the most fundamental processes in biochemistry. For enzymes, substrate binding is often coupled to conformational changes that alter the local environment of the active site to align the reactive groups for efficient catalysis and to reach the transition state. Adaptive substrate(More)
Peptide deformylase inhibitors (PDFIs) appear to be one of the most exciting classes of antibacterial agents discovered to date. Rapid progress in the development of PDFIs has been possible because peptide deformylase is a metalloprotease, and this class of enzymes shows a high degree of structure-function conservation, and because the most potent PDFIs are(More)
New classes of antibiotics are urgently needed to counter increasing levels of pathogen resistance. Peptide deformylase (PDF) was originally selected as a specific bacterial target, but a human homologue, the inhibition of which causes cell death, was recently discovered. We developed a dual-screening strategy for selecting highly effective compounds with(More)
