Overview of the metabolic pathways for glucose and ribose fermentation in L. sakei. Enzymes which expression is up- or down-regulated on ribose compared with glucose in the majority of the ten L. sakei strains (see Additional file 1, Table S2) are indicated with upward and downward pointing arrows, respectively. End-products are boxed. PTS, phosphotransferase system; T, transport protein; P, phosphate; B, bis; Glk, glucokinase; Pgi, phosphoglucoisomerase; Fbp, fructose-1,6-bisphosphatase; Pfk, 6-phosphofructokinase; Fba, fructose-bisphosphate aldolase; RbsU, ribose transporter; RbsD, D-ribose pyranase; RbsK, ribokinase; Rpi, ribose-5-phosphate isomerase; Rpe, ribulose-phosphate 3-epimerase; Xpk, xylulose-5-phosphate phosphoketolase; Tpi, triose-phosphate isomerase; GapA, glyceraldehyde-3-phosphate dehydrogenase; Pgk, phosphoglycerate kinase; Gpm3, phosphoglycerate mutase; Eno, enolase; Pyk, pyruvate kinase; LdhL, L-lactate dehydrogenase; PdhBD, pyruvate dehydrogenase complex subunits B and D; Pox1,2, pyruvate oxidase; Ack, acetate kinase; GlpD, glycerol-3-phosphate dehydrogenase; GlpK, glycerol kinase; GlpF, glycerol uptake facilitator protein.
