Gene expression profiling of Escherichia coli expressing double Vitreoscilla haemoglobin
In a recent investigation, expression of a double Vitreoscilla haemoglobin (two fused VHb molecules) in Escherichia coli grown in shake flasks resulted in higher final cell density and considerably higher levels of ribosomes and tRNA. In this study, we have investigated the E. coli transcriptome in cells expressing native VHb, double VHb and control cells lacking VHb by hybridising mRNA from the d
