Genome-wide peptidoglycan profiling of Vibrio cholerae

The paper develops a high-throughput peptidoglycan analysis pipeline to systematically study V. cholerae's genome-wide peptidoglycan homeostasis and identifies novel genetic determinants and a bifunctional penicillin-binding protein.

L-arabinose induces the formation of viable non-proliferating Vibrio cholerae spheroplasts

This study shows that L-arabinose induces the formation of viable non-proliferating V. cholerae spheroplasts that can resume growth when L-arabinose is removed.

Modulation of peptidoglycan synthesis by recycled cell wall tetrapeptides

This study identifies LdcV as a key enzyme in Vibrio cholerae that cleaves recycled murotetrapeptides, showing its role in maintaining cell wall integrity and synthesis by preventing toxic accumulation of tetrapeptide intermediates.

The cell division factor ZapB is required for bile resistance in Salmonella enterica

This study shows that ZapB, a cell division factor in Salmonella enterica, is required for bile resistance, with its mRNA stability regulated by MicA sRNA in response to bile salts.

Muropeptides Stimulate Growth Resumption from Stationary Phase in Escherichia coli

This study identifies muropeptides as a universal cue for bacterial growth resumption from stationary phase in E. coli and other species.
