Linear schematic representation of IncQ plasmids RSF1010, pIE723, pPSTRAS1, Pae-32183cz and pWES-1. The IncQ plasmid backbone is composed of genes involved in the mobilization of IncQ plasmids (mobC and mobB) and genes required for replication (repB, orfE, orfF, repA and repC) (hatched arrows). The oriV (replication) and oriT (mobilization) regions are represented by grey boxes. Accessory genes are represented by white arrows, except for blaCTX-M genes that are represented by black arrows. IRR of Tn5393 and IRR of ISEcp1 are indicated by vertical bars. Grey areas correspond to 100% sequence identity.
