Figure 2. Organization of cyanobacterial bacteriocin gene clusters.

Figure 2

The putatively identified gene clusters in this study were classified into seven groups (from I to VII) based on their gene organization and domain composition. ORF sizes and directions are shown in relative scale with color definition as precursor in red, ABC transporter in blue, HlyD in orange, SurA in green, LanM in pink, S8 peptidase-containing protein in yellow, other modification enzymes in purple, adjacent ORFs in black, and tRNA gene in light green. Domains involved in cyanobacterial bacteriocin production and modification are demonstrated within the ORFs with different colors, domain names are derived from the Conserved Domain Database [35]. (I) An example structure of group I from strain Synechococcus PCC 7335, and the locus_tag of hlyD is S7335_4080. (II) from Anabaena variabilis ATCC 29413, and the locus_tag of hlyD is Ava_4382. (III) from Nostoc sp. 7120, and the locus_tag of hlyD is alr5148. (IV) from Nostoc punctiforme PCC 73102, and the locus_tag of hlyD is Npun_F5048. (V) from Nostoc punctiforme PCC 73102, and the locus_tag of hlyD is Npun_R1804. (VI) from Anabaena variabilis ATCC 29413, and the locus_tag of the S8 peptidase domain-containing protein is Ava_4226. (VII) from Trichodesmium erythraeum IMS101, and the locus_tag of hlyD is Tery_0894.
