The antibiotic globomycin, an inhibitor of LspA (the lipoprotein signal peptidase), inhibited synthesis of colicin by Escherichia coli cells grown in rich medium. This inhibition was stronger in cells with mutation(s) within either the colicin operon, which is located on a plasmid, or the host chromosome. This phenotype was called Gbc (globomycin b...
Bacterial lipoproteins are characterized by fatty acids that are covalently attached to their amino terminus via posttranslational modification in the cytoplasmic membrane. Three enzymatic steps are involved in the synthesis of mature triacylated lipoprotein: prolipoprotein converts into diacylglyceryl-prolipoprotein that in turn converts into apol...

Discovery of novel classes of Gram-negative antibiotics with activity against multi-drug resistant infections is a critical unmet need. As an essential member of the lipoprotein biosynthetic pathway, lipoprotein signal peptidase II (LspA) is an attractive target for antibacterial drug discovery, with the natural product inhibitor globomycin offerin...
