Differentiation of ncRNAs from small mRNAs in Escherichia coli O157:H7 EDL933 (EHEC) by combined RNAseq and RIBOseq – ryhB encodes the regulatory RNA RyhB and a peptide, RyhP

Table 4 Competitive index values (CI) for EHEC strains possessing a wild-type like ORF encoding RyhP (P1 or P2) or an ORF with a premature stop codon (T2 or T3) plusminus their standard deviations (Std)

Wild-type like RyhP-ORF	Terminated RyhP-ORF	CI	±Std
P1	T2	0.79	0.08
P1	T3	0.19	0.08
P2	T3	0.38	0.06

Strains are competitively grown in minimal medium M9 with no iron added for 24 h. The RyhP-encoding ORF was transcriptionally induced with 0.2% arabinose
