Table 7.

Genes with less abundant mRNA (<60 percentile rank) and highly abundant proteins (>80 percentile rank)—butanol stress

Gene	Function	RBS score
CAC0108 a	ABC transporter	12.87
CAC0091 b	IlvC	12.38
CAC1301 a	Hypothetical	9.25

Genes are in italics to indicate their differential proteomic upregulation, while bold represents proteins that were expressed only under butyrate stress and lacked expression under control condition. Bold italics represent non-significant protein expression

^a5′UTR was not determined due to lack of sufficient data (reads) for CAC0108 and CAC1301

^bCAC0091 had a 5′UTR of 206 under non-stress condition but was found to be leaderless under butanol stress
