FIG 4.

Regulation of fab genes by FabT. (A) The Fab cluster of GAS, showing the locations of three putative FabT-binding DNA sequences (asterisks) located in front of phaB, fabT, and fabK. fabT is depicted in red. (B) Fold expression of each gene at both temperatures and phases of growth. The values in red indicate either that the differential fold expression was below the allotted 1.5 or that the P value was excluded after applying the Bonferroni correction. (C) Figure representing the regulatory regions of phaB, fabT, and fabK, with putative promoter sequences and FabT-binding DNA sequences indicated. Nucleotide residues matching the promoter sequence and FabT site are indicated in blue and red, respectively.
