(A) Cartoon image comparing the predicted functional domains of RscS (brown: PAS,
HisKA, HATPase_c, REC, Hpt), SypF (orange: HAMP, HisKA, HATPase_c, REC, HPt),
and an RscS-SypF chimera that contains the N-terminal regions of RscS and the
HPt domain of SypF. Grey boxes indicate transmembrane regions that flank a
putative periplasmic domain. (B) Wrinkled colony formation of WT (ES114) or
sypF deletion (KV5367) cells overproducing RscS (pARM7) or
the RscS-SypF chimera (pANN69). Indicated strains were spotted and grown for 22
hours.
