From: TonB-dependent transporters and their occurrence in cyanobacteria
The genomic structure of the loci coding for TonB-dependent transporters (TBDTs) in Anabaena sp. PCC 7120. For A-C, the genomic structure was excised from Cyanobase (http://bacteria.kazusa.or.jp/cyano/[148]) and the nomenclature of the colour code is given in C. White boxes indicate genes for which the name is given in the figure. (A) Shows the genomic orientation surrounding all2620 (top) and the sequencing profile of the region coding for the stop codon (in reverse orientation, bottom). (B) Shows the genomic orientation surrounding alr4028 (top) and the sequencing profile of the region coding for the stop codon (in reverse orientation, bottom). (C) The genomic organization surrounding the 22 other genes coding for TBDTs.
