Fig. 2
Predicted potential transcription factor binding sites (TFBSs) of SacR1 and SacR2 in the sacPTS1 and sacPTS26 clusters of L. plantarum ST-III. Putative TFBSs are underlined in red. The red backgrounds indicate the scores for each TFBS, defined as the sum of the positional nucleotide weight. The presumed start codon of each gene is shown in uppercase letters, and the putative -10 and -35 promoter regions and possible ribosome-binding sites (RBSs) are marked. Ppts1-sacA, Pagl4, PsacR2 in the black box represent the promoter regions
