Figure 4.

Starch, cellulose, hemicellulose, and glycogen degradation pathways of Achatina fulica were reconstructed from our bioinformatic analysis to perform metabolic pathway prediction on the basis of the giant snail genome. The pathways include enzyme names in abbreviation, metabolite intermediates with some structural representation, and arrows determining the reaction direction. Polysaccharide degradation, glycolysis, gluconeogenesis, and pentose phosphate pathways were represented by brown, green, pale pink, and bright pink arrows. Asterisks (*) indicate the enzymes with high copy numbers.
