Escherichia coli - Expression Data Matrix smd4502 (m4502): ProcessingTranscript profiles of Matrix smd4502 (m4502) were derived from the Stanford Microarray Database (SMD, Sherlock et al., 2001). Gene expression was analysed by colour-coded cDNA hybridisation technology. Experiments were mainly related to amino-acid metabolism (Khodursky et al., 2000), DNA metabolism (Courcelle et al., 2001), and RNA decay (Bernstein et al., 2002). Individual spots were quality checked as recommended by the SMD tutorial. In order to reduce the number of missing data smd4502 (m4502) was designed to maximise the number of genes, comprised 34 experiments, which were described by 1845 genes (Steinhauser et al., 2004a). Normalised gene expression ratios (Rat2N) were log base 2 transformed. Co-Response analyses were performed on range normalised (genes) matrix.
