Organization of the amb gene cluster in the Pseudomonas aeruginosa strain PAO1. The ambA gene encodes a putative LysE-type transmembrane protein potentially involved in AMB export, ambB and ambE code for non-ribosomal peptide synthetases (NRPS), and ambC and ambD specify two putative iron (II)/α-ketoglutarate-dependent oxygenases. The modular structures of AmbB and AmbE are shown with domains for adenylation (A), thiolation (T), condensation (C), methylation (MT), and thioester cleavage (TE). Note that AmbE may have an additional domain of unknown function at its N-terminus and that the C domain (indicated as C*) is atypical (see text for details).
