WebAug 1, 1996 · The putative repressor TxaR was expressed in Escherichia coli but deletion and frameshift mutations abolishing TxaR production had no effect on toxA expression. Naturally occurring non-toxigenic mutants which contained the toxA gene had no large rearrangements near toxA or changes in toxA promoter structure. WebMay 29, 2014 · This region contains a synthetic green fluorescent protein ( sgfp) gene under control of the strong and constitutive ToxA promoter from Pyrenophora tritici-repentis and a hygromycin B phosphotransferase ( hph) gene under control of the constitutive promoter pdgp from Agaricus bisporus.

WebMar 18, 1998 · There is a helix-turn-helix motif typical of LysR regulators (and DNA binding proteins in general) at the amino terminus of PtxR. Since PtxR, however, has not yet been purified, DNA binding studies have not yet been done on the regA or toxA promoters. It is also not clear whether ptxR is involved in the iron-regulated phase of toxA expression .
