Abstract
Arginine-rich histones (F3) interact with both the bacterial and mammalian RNA polymerase and inhibit the in vitro RNA synthesis to a much greater extent than when associated with the DNA template. The lysine-rich histones (F1) inhibit the RNA synthesis mainly through template inhibition. Neither histone fraction displayed such an interaction with DNA polymerase. The RNA polymerase-F3 histone interaction takes place at ionic strength equal to or greater than those occurring in living cells, suggesting a possible role of arginine-rich histones in the regulation of RNA synthesis.Entities:
