FIG. 2.

(A) Genetic organization of the L. lactis cellobiose operon. The putative −35 and −10 boxes in the promoter region of the L. lactis MG1363 catabolite-controlled ptcC gene are underlined. ptcB, cellobiose-specific PTS IIB component; ptcA, cellobiose-specific PTS IIA component; llmg_0439, putative DNA-binding transcriptional regulator; ptcC, cellobiose-specific PTS IIC component; bglA (annotated as celA), phospho-β-glucosidase. The putative cre site is indicated in the box. Asterisks indicate the mutations mapped in L. lactis NZ9000. (B to D) Typical growth profiles of L. lactis NZ9000 (•) and MG1363 (○) cultivated in CDM supplemented with 1% glucose (B), 1% cellobiose (C), or 1% cellobiose plus 0.1% glucose (D). All cultures were grown as biological triplicates, and average values are plotted.
