Figure 1.

Organization of the gal–lac operon with surrounding genes in L. lactis IL1403. Lollipops and brackets indicate potential transcription terminators. Bent arrows and underlined nucleotides indicate potential promoter regions. White‐on‐black font marks START and STOP codons. RBS indicates ribosome‐binding site. Vertical lines and underlined cre indicate catabolite responsive element with cre consensus sequence (WGWAARCGYTWWMA). The picture presents the correct sequence of lacS, which at the NCBI database is annotated as a pseudogene due to the deletion of an adenine 446. We confirmed correctness of lacS by its sequencing
