Origins of replication were identified with a consensus Origin Recognition Box (ORB) motif recently identified from active replication origins of Thaumarchaeota (Nitrosopumilus maritimus), Crenarchaeota and Euryarchaeota [ 40].
These experimental data revealed that the basic structure of replication origins is conserved among archaea, normally containing an AT-rich unwinding element and several conserved repeats (Origin Recognition Box, ORB) [ 9].
However, examination of the sequence of S. islandicus oriC2 reveals that one of the characterized mini origin recognition box (mORB) Orc1-1 binding sites has several base substitutions in conserved positions in the binding site when compared with S. solfataricus oriC2.
In this research, we designed a group of duplex DNA substrates containing specific origin recognition boxes (ORBs) of the archaeon and identified the DNA-binding activities of different SsoCdc6 proteins.
The source was placed at the origin, the boxes were placed with their centres at 50 cm intervals along the x axis, whilst the detector was set on the x = 0 plane.
Along with the improvements in critical reception, The Wolverine outgrossed Origins in box office returns.
Fighting games find their origin in boxing games but evolved towards battles between characters with fantastic abilities and complex special maneuvers.
The fine mapping of the three replication origins in Sulfolobus solfataricus led to the identification of origin recognition boxes (ORBs) and mini-ORBS [23].
The characterized archaeal origins are normally conserved in structure but vary in sequence among different origins in terms of origin recognition boxes (ORBs) and origin-associated initiator genes (Wu et al. 2012).
Multiple orc/cdc6-associated replication origins were predicted in all of the analyzed haloarchaeal genomes following the identification of putative ORBs (origin recognition boxes) that are associated with orc/cdc6 genes.
