Design Notes
The sequence immediately downstream of the p15a origin in this plasmid is an almost exact match to the AmpR cassette (see BBa_P1002). It seems likely that the orignal definition of the p15a origin was generous and could likely be truncated.

In 2017, Philippe Hansen-Estruch from the CCA_San_Diego team created a new plasmid based off the pSB3K3 plasmid. The p15A origin of replication was replaced with a RK2 origin of replication. The goal of this improvement was to replace p15a origin of replication (ori) with the RK2 ori to generate a shuttle vector as a broad host range vector (i.e. can replicate in E.coli and other microorganisms).
The RK2 origin of replication is a broad-host-range plasmid belonging to the incP incompatibility group that can be maintained in a large number of bacteria. The minimal region for replication and maintenance consists of an origin of replication, oriV, and the plasmid replication initiator protein TrfA protein, that activates oriV. The copy number of RK2 is about 4-7 per cell in E. coli, 3 in Pseudomonas aeruginosa, and 4-7 in Agrobacterium.
