...Eman I. Hassanen; Eman A. Morsy; Ahmed M. Hussien; Khaled Y. Farroh; Merhan E. Ali Escherichia coli infection is considered one of the most economically important multi-systemic diseases in poultry farms. Several nanoparticles such as silver, chitosan, and copper oxide are known to be highly toxic...

...-glycosidases, which also use NAD + as a cofactor. Both 2,7-AN and 2,3-EN support the growth of Escherichia coli provided the repressor NanR, which negatively controls the expression of the yjhBC operons, has been inactivated. Inactivation of either YjhC or YjhB in NanR-deficient cells prevents the growth...

...-directed mutagenesis, the natural variation in these residues and the effect on product composition were investigated. Fifteen MAM1 variants as well as the native MAM1 and MAM3 from A. thaliana were characterised by heterologous expression of the glucosinolate chain elongation pathway in Escherichia coli...

... production. This review describes current strategies for expression of P450s in the microbial cell factories Escherichia coli, Saccharomyces cerevisiae , and Pichia pastoris . Most eukaryotic P450s are membrane bound, the majority of them being natively located in the endoplasmic reticulum, whereas...

... homologous miRNAs (miR-192 and miR-215) was up-regulated in weaned piglets with Escherichia coli F18 infection. However, the potential molecular mechanism of miR-192 in regulating E. coli infection remains unclear in pigs. In the present study, we analyzed the relationship between level of miR-192 and degree...

...Lorenzo Randi; Alessandro Perrone; Mirko Maturi; Fabrizio Dal Piaz; Michela Camerani; Alejandro Hochkoeppler We report in the present study on the catalytic properties of the Deinococcus radiodurans DNA polymerase III α subunit (αDr). The αDr enzyme was overexpressed in Escherichia coli , both...

... Gly 602 and Lys 604 , helix α3 and the following loop have no contact with the remaining part of the RNase H domain. Bound cadmium ions are not found in this region, implying that this region is in a native conformation. Escherichia coli murine leukaemia virus reverse transcriptase...

... 2012 GroEL is a protein from Escherichia coli whose synthesis is stimulated under stressful conditions, including oxidative stress. Numerous studies have shown that the chaperonin GroEL binds to the non-native state of substrate polypeptides and hence prevents their aggregation in vivo [ 1...

...Syuzanna Blbulyan; Arev Avagyan; Anna Poladyan; Armen Trchounian Escherichia coli is able to ferment glycerol and produce H 2 by different Hyds (hydrogenases). Wild-type whole cells were shown to extrude H + through the F 1 F o -ATPase and by other means with a lower rate compared with that under...

...Nelli Mnatsakanyan; Karine Bagramyan; Anait Vassilian; Robert K. Nakamoto; Armen Trchounian The single cysteine in the b subunit of the membranous F 0 sector and the 19 cysteines in extramembranous F 1 sector of the Escherichia coli ATP synthase were replaced by alanine. When cells were grown under...

...Armen Trchounian; Hiroshi Kobayashi Escherichia coli accumulates K + by means of multiple transportsystems, of which TrkA is the most prominent at neutral and alkalinepH while Kup is major at acidic pH. In the present study, K + uptakewas observed with cells grown under fermentative conditions...
