DnaA is a protein that activates initiation of DNA replication in bacteria. It is a replication initiation factor which promotes the unwinding of DNA at oriC. The onset of the initiation phase of DNA replication is determined by the concentration of DnaA. DnaA accumulates during growth and then triggers the initiation of replication. Replication begins with active DnaA binding to 9-mer repeats upstream of oriC. Binding of DnaA leads to strand separation at the 13-mer repeats. This

Initiator proteins

The initiator proteins are the proteins that recognize a specific DNA sequence within the origin of replication.The origin of replication is the site where the helicase attaches to the template strand and starts to unwind the DNA into two strands. The origin recognition complex (ORC), a multisubunit protein identified in Saccharomyces cerevisiae, binds to chromosomal replicators and is required for the initiation of cellular DNA replication. Complementary DNAs (cDNAs) encoding proteins related to the two largest subunits of ORC were cloned from various eukaryotes. RctB, the initiator of replication of Vibrio choleraechromosome 2 (chr2), binds to the origin of replication to specific 12-mer sites both as a monomer and a dimer. Binding to 12-mers is essential for initiation. The monomers also bind to a second kind of site, 39-mers, which inhibits initiation.

First, three initiation factor proteins (known as IF1, IF2, and IF3) bind to the small subunit of the ribosome. This preinitiation complex and a methionine-carrying tRNA then bind to the mRNA, near

Only one viral protein, the Replication initiator protein (Rep), is strictly required for viral replication to occur. In fact, Rep is the most conserved geminiviral protein and it is critical for assembly of viral replisomes , a complex of viral and host proteins that forms a DNA replication fork at viral DNA ( Rizvi et al., 2015 ; Ruhel and Chakraborty, 2019 ).
