Web5 mrt. 2013 · It has been proposed that Orc6 has two Cdt1-binding sites and thus recruits two Cdt1–MCM2–7 complexes simultaneously (Takara & Bell 2011). As described above, Orc6 is not required for association of ORC with origin DNA but it is required for the recruitment of helicase. DnaA consists mainly in two different forms, the active ATP-form and the inactive ADP. The level of active DnaA within a cell is low immediately after a cell has divided. Although the active form of DnaA requires ATP, the formation of the oriC/DnaA complex and subsequent DNA unwinding does not require ATP hydrolysis. The oriC site in E. coli has three AT rich 13 base pair regions (DUEs) followed by four 9 bp region…

A final subdivision is drawn on the basis of the direction of translocation; they can be distinguished as type A or type B helicases if they move on the substrate from 3′–5′ or …
WebInvolved in transcriptional regulation; the function is independent of the RNA helicase activity. Transcriptional coactivator for androgen receptor AR but probably not ESR1. … WebThere are 8 DnaA binding sites within oriC, to which DnaA binds with differential affinity. When DNA replication is about to commence, DnaA occupies all of the high and low affinity binding sites. The denatured AT-rich region allows for the recruitment of DnaB , which complexes with DnaC (helicase loader).
