title: Mutational analysis of the fic promoter recognized by RpoS (sigma 38) in Escherichia coli.
abstract: fic gene expression at the stationary phase is dependent on RpoS (sigma 38). For this paper, the fic promoter (P fic) mutants were isolated; C at the position -34 was changed into T. They did not show the stationary phase-specific expression dependent on RpoS in vivo. Furthermore, it was confirmed that they were recognized by E sigma 70 as efficiently as E sigma 38 in vitro.
