Biosynthesis of peptidoglycan requires carefully orchestrated transpeptidation reactions to maintain the structural integrity of this essential component of the bacterial cell wall. Now, rotor-fluorescent d-amino acids have been shown to enable real-time tracking of these transpeptidation reactions in live bacterial cells. These powerful tools allow visualization of peptidoglycan biosynthesis with high spatiotemporal resolution.
