CycA-Dependent Glycine Assimilation Is Connected to Novobiocin Susceptibility in Escherichia coli.

Microbiology spectrum 20221115 6

Escherichia coli serine hydroxymethyltransferase (GlyA) converts serine to glycine, and glyA mutants are auxotrophic for glycine. CycA is a transporter that mediates glycine uptake. Deleting glyA in E. coli strain W3110 led to activation of CysB, which was related to novobiocin (NOV) susceptibility. Moreover, deleting glyA resulted in increased sensitivity to NOV, and this could be reversed by high concentrations of glycine. Reverse mutants of ΔglyA were selected and ...[more]

Comparison of Escherichia coli K-12 tynA- with wild type Escherichia coli K-12

Project description:Escherichia coli (E. coli) amine oxidase (ECAO) encoded by tynA gene has been one of the model enzymes to study the mechanism of oxidative deamination of amines to the corresponding aldehydes by amine oxidases. The biological roles of ECAO have been less addressed. Therefore we have constructed a gene deletion Escherichia coli K-12 strain, E. coli tynA-, and used the microarray technique to address its function by comparing the total RNA gene expression to the one of the wt. Our results suggest that tynA is a reserve gene for stringent environmental conditions and its gene product ECAO a growth advantage compared to other bacteria due to H2O2 production.

Transcriptome analysis of Escherichia coli O157:H7 EDL933 during heat shock using microarrays

Project description:The transcriptome of Escherichia coli K-12 has been widely studied over a variety of conditions for the past decade while such studies involving E. coli O157:H7, its pathogenic cousin, are just now being conducted. To better understand the impact of heat shock on E. coli O157:H7, global transcript levels of strain EDL933 cells shifted from 37°C to 50°C for 15 min were compared to cells left at 37°C using microarrays. Keywords: Stress Response

Expression analysis of Escherichia coli MG1655 K-12 M-bM-^HM-^Fhns/M-bM-^HM-^FstpA from aerobic and anaerobic growth conditions

Project description:Investigation of whole genome gene expression level changes in a Escherichia coli MG1655 K-12 M-bM-^HM-^Fhns/M-bM-^HM-^FstpA strain from exponental growth under aerobic and anaerobic growth conditions. The results are further described in the article Genome-scale Analysis of E.coli FNR Reveals the Complex Features of Transcrtipion Factor Binding. A four chip study using total RNA recovered from two separate cultures of Escherichia coli MG1655 K-12 M-bM-^HM-^Fhns/M-bM-^HM-^FstpA mutant strain under aerobic and anaerobic growth conditions. Each chip measures the expression level of 4,661 genes from Escherichia coli MG1655 K-12 using a high-density tiling array consisting of ~385,000 60mer probes spaced every 12 bp.
