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. too many supplements at once bodybuildingWitrynaOriV: replication origin; ColE1: pBR322 replication origin; TrfA: Replication essential locus; NPT: neomycin phosphotransferase gene conferring resistance to kanamycin; and Nos: nopaline synthase terminator sequence.
