Figure 2From: Replicating DNA by cell factories: roles of central carbon metabolism and transcription in the control of DNA replication in microbes, and implications for understanding this process in human cellsFactors and processes influencing transcriptional activation of the origin and replication complex (RC) function in bacteriophage λ DNA replication. Positive regulations are marked by arrows, and negative regulations are symbolized by blunt-ended lines. Host-encoded and host-produced factors are marked in blue, bacteriophage-encoded factors – in red, and physical factors – in green. For detailed review on the transactions depicted in this scheme, see ref.[64].Back to article page
