DNA Sequence:

Origin Sequence Elements: ACS confirmed.

Helical Stability: Minimum -144.3 ΔG° (kcal/mol) at location 14704.

Time of Origin Replication (Trep): This site was not identified as an origin by any curated timing study (Raghuraman et al. (2001); Yabuki et al. (2002); Alvino et al. (2007)), suggesting that this site is not chromosomally active for replication initiation.

Origin activity in HU: Origin activity detected in HU — more details.

Thursday, 17th August 2006 - Conrad Nieduszynski:

2D gel analysis indicates that ARS302 (like ARS301, ARS303 & ARS320) does NOT normally serve as chromosomal replication origin (see Dubey et al., 1991 in References tab). [Thanks to Joel Huberman & Carol Newlon for this information.]
