Abstract:
BACKGROUND: Diverse datasets, including genomic,
transcriptomic, proteomic and metabolomic data, are becoming
readily available for specific organisms. There is currently a
need to integrate these datasets within an in silico modeling
framework. Constraint-based models of Escherichia coli K-12
MG1655 have been developed and used to study the bacterium's
metabolism and phenotypic behavior. The most comprehensive E.
coli model to date (E. coli iJE660a GSM) accounts for 660 genes
and includes 627 unique biochemical reactions. RESULTS: An
expanded genome-scale metabolic model of E. coli (iJR904
GSM/GPR) has been reconstructed which includes 904 genes and
931 unique biochemical reactions. The reactions in the expanded
model are both elementally and charge balanced. Network gap
analysis led to putative assignments for 55 open reading frames
(ORFs). Gene to protein to reaction associations (GPR) are now
directly included in the model. Comparisons between predictions
made by iJR904 and iJE660a models show that they are generally
similar but differ under certain circumstances. Analysis of
genome-scale proton balancing shows how the flux of protons
into and out of the medium is important for maximizing cellular
growth. CONCLUSIONS: E. coli iJR904 has improved capabilities
over iJE660a. iJR904 is a more complete and chemically accurate
description of E. coli metabolism than iJE660a. Perhaps most
importantly, iJR904 can be used for analyzing and integrating
the diverse datasets. iJR904 will help to outline the
genotype-phenotype relationship for E. coli K-12, as it can
account for genomic, transcriptomic, proteomic and fluxomic
data simultaneously.

Project description:Bacterial transcription factors (TFs) regulate gene expression to adapt to changing environments; when combined, the TF’s regulatory actions comprise transcriptional regulatory networks (TRNs). The chromatin immunoprecipitation (ChIP) assay is the major contemporary method for mapping in vivo protein-DNA interactions in the genome. It enables the genome-wide study of transcription factor binding sites (TFBSs) and gene regulation. Although rapidly accumulating publicly-available ChIP data are a valuable resource for the study of gene regulation, there are no full datasets of key regulators in E. coli K-12 MG1655. Here, we present the genome-wide binding for major TFs in the E. coli K-12 MG1655.

Project description:The number and overlapping substrate repertoire of multidrug efflux pumps in the E. coli genome suggest a physiological role apart from multidrug resistance. This role was investigated using transcriptomic analyses of cDNAs labeled from E. coli AG102 mRNA (hyper drug resistant, marR1) and its isogenic major efflux pump mutants. Keywords: Mutation Analysis

Project description:We report the effect of oxygenation state in lactose grown escherichia coli producing recombinant proteins. To shed more light on the mechanistic correlation between the uptake of lactose and dissolved oxygen, a comprehensive study has been undertaken with the E. coli BL21 (DE3) strain. Differences in consumption pattern of lactose, metabolites, biomass and product formation due to aerobiosis have been investigated. Transcriptomic profiling of metabolic changes due to aerobic process and microaerobic process during protein formation phase has been studied and the results provide a deeper understanding of protein production in E. coli BL21 (DE3) strains with lactose based promoter expression systems.This study also provides a scientific understanding of escherichia coli metabolism upon oxygen fluctuations.
