FIG 7.

Model of C. phytofermentans hexose metabolism. Polysaccharides are degraded by CAZymes belonging to multiple glycoside hydrolase (GH) and polysaccharide lyase (PL) families. ABC transporters and metabolic enzymes are shown with NCBI GenBank numbers (blue) and associated production (green) or consumption (red) of ATP, NADH, and reduced ferredoxin. glu, glucose; gal, galactose; gala, galacturonic acid; cb, cellobiose; glu_n, cellodextrin; gal_n, galacto-oligosaccharide; galA_n, galacturono-oligosaccharides; glu1P, glucose-1-phosphate; glu6P, glucose-6-phosphate; gal1P, galactose-1-phosphate; G3P, glyceraldehyde-3-phosphate; ac-CoA, acetyl coenzyme A; Fd⁻, reduced ferredoxin.
