Abstract Heterologous gene expression can be a significant burden for cells. Here we describe an in vivo monitor that tracks changes in the capacity of Escherichia coli in real time and can be used to …

ed bacteria all heterologous expression represents an unn 15 consuming cellular resources usually allocated to replication, repair and native gene expression ssion burden is a well-known …

Figure 1 : The capacity available for E. coli gene expression can be indirectly measured to quantify burden. Figure 2 : Relationships among capacity, growth rate and construct output for a …

However, for engineered bacteria, all heterologous expression represents an unnatural load, consuming cellular resources and leading to decreased growth rates that can predispose synthetic ...

Mar 18, 2015 · Results We have followed a typical fed-batch induction regime for heterologous protein production under the control of the AOX1 promoter using both microarray and metabolomic analysis. …

Jun 26, 2015 · Background Predictable control of gene expression is necessary for the rational design and optimization of cell factories. In the yeast Saccharomyces cerevisiae, the promoter is one of the …

In bacterial cells, substanal progress towards increasing the predictability of gene expression has been made by showing that exogenous genec material imposes a significant burden, resulng in …

Oct 1, 2016 · The predictability and robustness of engineered bacteria depend on the many interactions between synthetic constructs and their host cells. Expression from synthetic constructs is an …

Heterologous gene expression can be a significant burden to cells, consuming resources and causing decreased growth and stability. We describe here an in vivo monitor that tracks E. coli capacity …
