A hybrid bacterial replication origin.

We constructed a hybrid replication origin that consists of the main part of oriC from Escherichia coli, the DnaA box region and the AT-rich region from Bacillus subtilis oriC. The AT-rich region could be unwound by E. coli DnaA protein, and the DnaB helicase was loaded into the single-stranded bubble. The results show that species specificity, i.e. which DnaA protein can do the unwinding, resi...

Pseudomonas chromosomal replication origins: a bacterial class distinct from Escherichia coli-type origins.

The bacterial origins of DNA replication have been isolated from Pseudomonas aeruginosa and Pseudomonas putida. These origins comprise a second class of bacterial origins distinct from enteric-type origins: both origins function in both Pseudomonas species, and neither functions in Escherichia coli; enteric origins do not function in either pseudomonad. Both cloned sequences hybridize to chromo...

Activation of a human chromosomal replication origin by protein tethering

The specification of mammalian chromosomal replication origins is incompletely understood. To analyze the assembly and activation of prereplicative complexes (pre-RCs), we tested the effects of tethered binding of chromatin acetyltransferases and replication proteins on chromosomal c-myc origin deletion mutants containing a GAL4-binding cassette. GAL4(DBD) (DNA binding domain) fusions with Orc2...

Regulation of DNA Replication Origin Licensing

DNA replication is a fundamental biological process that serves to create two copies of the genetic material during each cell division. Complete and precise replication enables identical sets of genes to be faithfully delivered to daughter cells during each cell division. To achieve rapid duplication of the entire genome, eukaryotic cells initiate DNA replication at multiple locations on each c...

Transparent parallel replication of logically partitioned databases

This paper presents a protocol for efficient transaction management in an environment of replicated autonomous databases. Each replicated copy has ownership over mutually exclusive portions of the database. The protocol improves response time and throughput by exploiting parallelism although reducing the degree of transaction isolation. Most modifications to the database are assumed to be on th...
