Similarly, Orc2 started to be detected (∼3-fold enrichment) in early G1 and remained rather constantly bound to the origin.
In the budding yeast Saccharomyces cerevisiae, the ORC complex bound to the origin initiates Mcm2-7 heloadingloadinG in G <img src="http://journals.plos.org/plosone/article/asset?id=info?doi/10.1371/journal.pone.0010203.e001.PNG" class= inline-graphic"/> phase by recruiting specific licensing factors in the pre-replicative complex (pre-RC) [7].
The complex binds to the origin sequence called autonomously replicating sequence (ARS) in chromosomes of budding yeast.
An interesting possibility is that origin structure might be influenced by the different replication complexes or factors bound to the origin before and after origin firing.
CDC6 licenses DNA replication, and once it is bound to the origin recognition complex at the origins of replication, it commences recruitment, together with Cdt1 and the MCM complex[ 23, 24].
Nuclear factor I (NFI) was initially discovered as a cellular factor required for adenovirus DNA replication [ 1], where it binds to the origin of replication and recruits the viral DNA polymerase [ 2- 4].
Scientists have been studying attitudes and preferences for more than a century; those topics are bound to the origins of social psychology itself.
According to the Uniprot database (http://www.uniprot.org/, last accessed January 25 , 2013, all four proteins from group E contain the CRP-type HTH motif in the middle of the protein, suggesting that the HTH motif is used to bind to the plasmid replication origin.
CtrA binds to the chromosomal origin of replication and blocks replication initiation in the swarmer cell [34].
For example, the Caulobacter crescentus regulator CtrA both transcribes a set of genes involved in replication and binds to the chromosomal origin, silencing initiation of replication, and degradation of CtrA by the Clp proteases is needed for replication to begin [53].
