  • Title: [Studies on modulation and control sigma 38 and RMF for the expression of some genes].
    Author: Ding Q, Akira I.
    Journal: Wei Sheng Wu Xue Bao; 1996 Oct; 36(5):344-50. PubMed ID: 9639823.
    Abstract:
    The E. coli mutants and wild type strains of rpoS and rmf were cultured in rich medium LB and limited component medium EP respectively. During the stationary phase, the viable cells of mutants were less than wild type strains's. The change of the product of serial proteins was quantified with Western blot. Sigma 38 has not effects on the product of rpoA, rpoB, rpoC, groE and tu gene, depress the transcription of crp and promote the expression of rmf. RMF can promote expression of rpoA, rpoD, groEl, rho, ompA and tufA gene in rich medium, but not in limited medium, and then depress and promote the expression of crp and rpoS respectively.
