The cells were fractionated according to methods 1 (cold osmotic shock and freeze– thaw cycling), 2 (cold osmotic shock with magnesium and freeze–thaw cycling), 3 (EDTA/lysozyme/ cold osmotic shock and sonication) and 4 (EDTA/lysozyme/cold osmotic shock and freeze–thaw cycling). The fractions are represented as cytoplasmic (C), insoluble (I) and periplasmic (P). Western blots show from top to bottom, the detection of PhoA, PDI, Erv1p, G6PD, LacI, MBP and DsbA proteins as detected by anti-His, anti-cMyc, anti-cMyc, anti-G6PD, anti-LacI, anti-MBP and anti-DsbA antibodies, respectively.

Fig. 1. The upstream sequences of the Salmonella <t>Typhimurium</t> <t>LT2</t> metE+ gene and the FnrS sequences and its predicted secondary structure, using Mfold (http:://un- afold.rna.albany.edu). (A) The -35, -10 pro- moter and the SD sequence of the metE+ are marked by a filled line. The +1 is marked as the transcriptional start site and Met is the in- itial amino acid of the MetE protein. The metE::lacZ fusion plasmid includes that the metE+ promoter region is fused with the lacZ reporter gene by compatible EcoRI-BamHI sites. The black spots under the metE+ up- stream sequences are the putative com- plementary sequences for FnrS binding. (B) The nucleotide from 5′ end till position 46 is a stem-loop 1, the nucleotide 62 to 87 is a stem- loop 2, the nucleotide 95 to 114 is a stem-loop 3. The black dots indicate that the nucleotides of FnrS likely base-paired with the sequences of the metE+ 5′ mRNA.

Western blots show from top to bottom, the detection of PhoA, PDI, Erv1p, G6PD, LacI, MBP and DsbA proteins as detected by anti-His, anti-cMyc, anti-cMyc, anti-G6PD, anti-LacI, anti-MBP and anti-DsbA antibodies, respectively. Molecular weight markers are indicated on the right in kDa. WT: Wildtype.

(A) The -35, -10 pro- moter and the SD sequence of the metE+ are marked by a filled line. The +1 is marked as the transcriptional start site and Met is the in- itial amino acid of the MetE protein. The metE::lacZ fusion plasmid includes that the metE+ promoter region is fused with the lacZ reporter gene by compatible EcoRI-BamHI sites. The black spots under the metE+ up- stream sequences are the putative com- plementary sequences for FnrS binding. (B) The nucleotide from 5′ end till position 46 is a stem-loop 1, the nucleotide 62 to 87 is a stem- loop 2, the nucleotide 95 to 114 is a stem-loop 3. The black dots indicate that the nucleotides of FnrS likely base-paired with the sequences of the metE+ 5′ mRNA.
