Initiator proteins are key components of the DNA replication machinery that determine where initiation will occur. In the past few years, due to a greatly improved understanding of what viral

To address this deficiency, we designed the amino acid 4- (2′-bromoisobutyramido)phenylalanine (1) as an initiator in atom-transfer radical polymerization (ATRP) that would provide a stable linkage between the protein and growing polymer. The initiator protein is the only sequence specific DNA-binding protein involved in the initiation of replication. The model proposed that all the DNA replicated from a particular origin as a replicon. In prokaryotes since there is only one origin of replication at the single chromosome, the entire chromosome is a single replicon.

Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'-TTATC [CA]A [CA]A-3'. DnaA binds to ATP and to acidic phospholipids. 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 ). Multifunctional protein essential for viral DNA replication, which cooperatively interacts with the viral DNA origin of replication and transactivates several promoters including the viral p6 promoter (PubMed:27809499, PubMed:24418564, PubMed:11853402). The pir gene of plasmid R6K encodes the protein, π, a replication and transcription factor.

Although both proteins bind to a series of 22-bp direct repeats essential for plasmid R6K replication, only π35.0 can bind to a site in the (A⋅T)-rich 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.
