PLoS One
. 2017 Mar;
12(3):e0174130.
PMID: 28328998
Construction of a complex artificial self-replication system is challenging in the field of in vitro synthetic biology. Recently, we developed a translation-coupled RNA replication system, wherein an artificial genomic RNA...

82(1):33-44.
PMID: 25792768
The DNA-binding specificity of a transcription factor, the FFRP FL4 (pot1613368) from Pyrococcus sp. OT3, was studied. Using SELEX (systematic evolution of ligands by exponential environment) experiments, from a set...

Methods Mol Biol
. 2015 Feb;
1279:45-65.
PMID: 25636612
Here we describe the systematic identification of single genes and gene pairs, whose knockout causes lethality in Escherichia coli K-12. During construction of precise single-gene knockout library of E. coli...

Gene
. 2012 Apr;
502(1):27-35.
PMID: 22504029
Escherichia coli PhoB protein is the transcriptional activator of the phosphate (pho) regulon genes involved in phosphate utilization. To gain further insight into the potential roles of PhoB in the...

. 2011 Sep;
57(4):219-30.
PMID: 21914970
In Escherichia coli (E. coli), most DNA damage-inducible (din) genes belong to the LexA regulon, whose products are related to functions such as DNA repair and induced mutagenesis. The E....

PMID: 21538251
By using a lacZ operon fusion genomic library of the Escherichia coli 0157:H7 Sakai, we identified phosphate-starvation-inducible (psi) promoters located upstream of the yibD and ytfK genes. They have been...

PMID: 19468044
The DNA-binding mode of archaeal feast/famine-regulatory proteins (FFRPs), i.e. paralogs of the Esherichia coli leucine-responsive regulatory protein (Lrp), was studied. Using the method of systematic evolution of ligands by exponential...

PMID: 18239270
Feast/famine regulatory proteins (FFRPs) comprise a single group of transcription factors systematically distributed throughout archaea and eubacteria. In the eubacterial domain in Escherichia coli, autotrophic pathways are activated and heterotrophic...
