The number of valid protein identifications and significantly differentially expressed genes and proteins after temperature downshift of <i>E. coli</i> O157∶H7 Sakai from 35°C to 14°C.

aNumber of proteins identified in soluble (outside brackets) and membrane (within brackets) fractions of the proteome that have passed the filtering criteria. bNumber of protein identifications with high confidence in membrane, soluble and total fractions of the proteome. cAnalysis does not include the number of differentially expressed undefined intergenic regions in the transcriptome. dNumber of up-regulated (outside brackets) and down-regulated (within brackets) genes and proteins. eNumber of genes and proteins significantly up- or down-regulated in both the transcriptomic and proteomic analysis. eNA; not applicable.
