Analysis of expression and transcriptional coupling of bfp genes in Bacteroides fragilis. Horizontal open arrows represent the protease (white) and putative inhibitor (grey) genes. Small filled black arrows represent the positions of the oligonucleotide primers used in the reverse-transcription PCR analysis, the size of the expected amplicon is given in bp between the appropriate sets of pimers. The resulting PCR fragments are presented in the right-hand panels, above which the size markers are indicated.
