(A) Bacillibactin NRPS cluster from B. subtilis with the corresponding domain organization of synthetase modules. ICL, isochorismatase; C, condensation domain; T, thiolation domain. (B) Structure of the trilactone Bacillibactin, with one of the catecholic moiety activated by DhbE shaded in gray. (C) The DhbE-dependent aryl acid adenylation in peptide synthesis is an ATP-consuming process leading to a protein-bound adenylate.
