Figure 1.

Distribution of proteinase, peptide transporters and peptidases of the proteolytic system in LAB. The number of identified genes is indicated. MEROPS families are indicated for proteinase and peptidases. Color shading shows absence of a gene (white), a single gene (yellow) or multiple genes (green). The GI codes of the genes can be found in Additional File 2.
