Figure 1.

Linear map showing the genetic structure of circular plasmid pZM3H1. The predicted genetic modules are indicated by white rectangles: REP – replication system, CZC – cobalt, zinc and cadmium resistance module, β – putative beta-lactamase, MER – mercury resistance module, TA – toxin-antitoxin system, MOB – system for mobilization for conjugal transfer, PAR – partitioning system. Arrows indicate the transcriptional orientation of the genes. The plot shows the G+C content of the pZM3H1 sequence (mean value 57.6 mol%). The gray-shaded area connects genes of plasmid pZM3H1 and C. litoralis KT71 that encode orthologous proteins. Sequences and structures of cis-acting elements responsible for plasmid replication (oriV), maintenance (parS), mobilization (oriT), as well as elements of a putative transposon (IRL and res) are shown. DR – direct repeats within the REP module.
