abstract：:The antibiotic cerulenin markedly inhibits the growth of Escherichia coli. The effects of the antibiotic on cellular syntheses were studied by measuring the incorporation of labeled precursors into lipids and macromolecules. During the first 40 min after the addition of cerulenin to a culture of growing cells, lipid s...
