Salmonella Typhimurium Genes in rbs Operon That Are Regulated by luxS/Autoinducer-2 at Mid-Log Phase and Early Stationary Phases in Both the Absence and Presence of 0.5% Glucose

		Fold change W/M
		LB broth		LB broth + glucose
Genes	Putative identification of JCVI database	Mid-log	Early stationary	Mid-log	Early stationary	Fold change wCFS/mCFS
rbsA	ABC superfamily (atp_bind), D-ribose high-affinity transport protein	1.1	1.1a	–	1.1a	−1.1a
rbsB	ABC superfamily (peri_perm), D-ribose transport protein	2.0	–	–	–	1.1
rbsC	ABC superfamily (membrane), D-ribose high-affinity transport protein	−1.2a	1.2a	–	1.1a	1.0
rbsD	D-ribose high-affinity transport system membrane-associated protein	1.3a	–	–	1.1a	1.2
rbsK	Ribokinase	2.2	–	–	1.1a	1.2
rbsR	Transcriptional repressor for rbs operon (GalR/LacI family)	2.5	–	–	–	−1.1a

Differentially regulated genes between wild type (W) and ΔluxS mutant (M) and between wild-type cell-free supernatants and ΔluxS mutant cell-free supernatants are listed.
