WitrynaAn amplifiable pBAC/oriV system consists of the pBAC/oriV vector and a cognate host strain. The vector contains a new, additional origin of replication ( oriV) derived from a broad-host-range plasmid RK2 ( 5, 6 ). Medium copy number plasmids, also called relaxed plasmids, require a system to ensure that replication is inhibited once the number of plasmids in the cell reaches a certain threshold. Relaxed plasmids are generally regulated through one of two mechanisms: antisense RNA or iteron binding groups. Low copy number plasmids, also called stringent plasmids, require tighter control of replication. WitrynaThe actual origin of replication for BACs and F plasmids is called oriS, but there are several additional parts needed to make a functional plasmid. The repE gene encodes a protein that plays a similar role to what pi does for an R6K origin. The parA, parB, and parC help the plasmid stably partition to daughter plasmids during replication. how to calculate federal tax rate

The essential replication system in RK2 consists of an origin of replication, oriV, and a gene, trfA, whose gene product, the TrfA protein, binds to and activates oriV. In Escherichia coli, replication proceeds unidirectionally from oriV after activation by TrfA. In E. coli, multiple plasmid copies appear to cluster together, creating a few multiplasmid clusters in each cell. The copy number of RK2 is about 4-7 per cell in E. coli and 3 in P. aeruginosa.
