Fig. 2From: Discovery and overproduction of novel highly bioactive pamamycins through transcriptional engineering of the biosynthetic gene clusterSchematic organization of the pam BGC and the applied promoter engineering method. A Schematic representation of genetic and transcriptional organization of the pam BGC. Arrows shows the location of promoters identified by RNA-seq experiments (unpublished data).
