WikiGenes - oriV

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.

Plasmids 101: Origin of Replication - Addgene

Witryna12 sie 2008 · DNA replication of the broad-host-range plasmid RK2 is initiated by the binding of the plasmid-encoded protein TrfA to direct repeats (iterons) present at its replication origin ( oriV ), a process similar to that of other plasmid systems ( 1, 2 ). 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. kappa light chain level high

WitrynaBinds to 8 17-base pair repeat sequences (iterons) in the RK2 minimal replication origin (oriV), opening the origin of replication. oriV opening does not absolutely require the presence of nucleotides; formation of open complex is somewhat enhanced by ATP or ATP gamma S, while DnaA or HU is required for full opening. Witryna1 lut 2008 · Identification of replication origins ( oriC s) is necessary for almost all newly sequenced bacterial genomes. Given the increasing pace of genome sequencing, the current available software for predicting oriC s, however, still leaves much to be desired. law offices of tim powersWitryna1 mar 2012 · The AT-rich regions in bacterial chromosomal origins of replication are usually located on one side of a cluster of DnaA-box sequences. In case of the plasmid origins, this rule applies to the AT-rich region and the iteron sequences recognized by initiator proteins. law offices of tim misny willoughby oh
