Transcriptional regulation of the bgl operon of Escherichia coli involves phosphotransferase system-mediated phosphorylation of a transcriptional antiterminator.
Amster-Choder O, Wright A. Amster-Choder O, et al. Among authors: wright a. J Cell Biochem. 1993 Jan;51(1):83-90. doi: 10.1002/jcb.240510115. J Cell Biochem. 1993. PMID: 7679391 Review. No abstract available.
Modulation of transcription antitermination in the bgl operon of Escherichia coli by the PTS.
Raveh H, Lopian L, Nussbaum-Shochat A, Wright A, Amster-Choder O. Raveh H, et al. Among authors: wright a. Proc Natl Acad Sci U S A. 2009 Aug 11;106(32):13523-8. doi: 10.1073/pnas.0902559106. Epub 2009 Jul 24. Proc Natl Acad Sci U S A. 2009. PMID: 19633194 Free PMC article.
Nevertheless, the release of BglG from BglF, which is stimulated by the extracellular sugar in a sugar uptake-independent manner, is a prerequisite for BglG activation. Taken together, the results indicate that activation of BglG is a 2-stage process: a

A novel class of mutations that affect DNA replication in E. coli.
Nordman J, Skovgaard O, Wright A. Nordman J, et al. Among authors: wright a. Mol Microbiol. 2007 Apr;64(1):125-38. doi: 10.1111/j.1365-2958.2007.05651.x. Mol Microbiol. 2007. PMID: 17376077
Based on the assumption that suppressors of the cold-sensitive phenotype of the cos mutant should include mutations that affect the efficiency and/or regulation of DNA replication, we subjected a dnaA(cos) mutant strain to transposon mutagenesis and selected mutant derivat …

Polar localization of the Escherichia coli oriC region is independent of the site of replication initiation.
Gordon GS, Shivers RP, Wright A. Gordon GS, et al. Among authors: wright a. Mol Microbiol. 2002 Apr;44(2):501-7. doi: 10.1046/j.1365-2958.2002.02901.x. Mol Microbiol. 2002. PMID: 11972786
Thus, we propose that positioning of the wild-type origins at the poles is not a function of their order of replication but a sequence-specific phenomenon. ...

The relationship between dNTP pool levels and mutagenesis in an Escherichia coli NDP kinase mutant.
Nordman J, Wright A. Nordman J, et al. Among authors: wright a. Proc Natl Acad Sci U S A. 2008 Jul 22;105(29):10197-202. doi: 10.1073/pnas.0802816105. Epub 2008 Jul 10. Proc Natl Acad Sci U S A. 2008. PMID: 18621712 Free PMC article.
A human homologue of Ndk and potential suppressor of tumor metastasis, nm23-H2, can complement the mutagenic phenotype of an E. coli ndk mutant. ...We show that loss of ndk function is synergistic with a dut-1 mutation and synthetically lethal with the loss of thymi

The BglF sensor recruits the BglG transcription regulator to the membrane and releases it on stimulation.
Lopian L, Nussbaum-Shochat A, O'Day-Kerstein K, Wright A, Amster-Choder O. Lopian L, et al. Among authors: wright a. Proc Natl Acad Sci U S A. 2003 Jun 10;100(12):7099-104. doi: 10.1073/pnas.1037608100. Epub 2003 May 27. Proc Natl Acad Sci U S A. 2003. PMID: 12771379 Free PMC article.
The Escherichia coli BglF protein is a sugar-sensor that controls the activity of the transcriptional antiterminator BglG by reversibly phosphorylating it, depending on beta-glucoside availability. BglF is a membrane-bound protein, whereas BglG is a soluble p …

Kinetics of plasmid segregation in Escherichia coli.
Gordon S, Rech J, Lane D, Wright A. Gordon S, et al. Among authors: wright a. Mol Microbiol. 2004 Jan;51(2):461-9. doi: 10.1046/j.1365-2958.2003.03837.x. Mol Microbiol. 2004. PMID: 14756786
Production of a GFP-Lac repressor hybrid protein in cells carrying F or P1 plasmids tagged with a lac operator array reveals that in smaller (younger) cells these plasmids are seen mainly as a single fluorescent focus at mid-cell, whereas larger cells tend to …

Escherichia coli nucleoside diphosphate kinase mutants depend on translesion DNA synthesis to prevent mutagenesis.
Nordman J, Wright A. Nordman J, et al. Among authors: wright a. J Bacteriol. 2011 Sep;193(17):4531-3. doi: 10.1128/JB.05393-11. Epub 2011 Jul 1. J Bacteriol. 2011. PMID: 21725024 Free PMC article.

Chromosome and low copy plasmid segregation in E. coli: visual evidence for distinct mechanisms.
Gordon GS, Sitnikov D, Webb CD, Teleman A, Straight A, Losick R, Murray AW, Wright A. Gordon GS, et al. Among authors: wright a. Cell. 1997 Sep 19;90(6):1113-21. doi: 10.1016/s0092-8674(00)80377-3. Cell. 1997. PMID: 9323139
We have investigated DNA segregation in E. coli by inserting multiple lac operator sequences into the chromosome near the origin of replication (oriC), in the hisC gene, a terminus marker, and into plasmids P1 and F. Expression of a GFP-LacI fusion protein allowed v …
