Bacterial cell model. Cell cycle parameters and macromolecular synthesis.

摘要: Abstract A repliconic Helmstetter type model for the E. coli cell cycle is considered. In this syntheses of various enzymes compete a common precursor and transcription rate limited by cellular quantity RNA polymerase. Enrichment nutritive medium considered to turn off synthesis several thus favour activity directly involving division. The predicts division rate, μ, inversely proportional total genome activation degree, Σ i ; volume ploidy constant at low rates μ high rates, explains why size composition do not depend much on temperature.
