Kontrollierter Transport und lichtinduzierte Freisetzung von Magic Spot Nukleotiden in Escherichia coli

open access: yesAngewandte Chemie, Volume 138, Issue 15, 6 April 2026.
We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a
