Some taxa known to possess this pathway include ? : Euglena gracilis

Expected Taxonomic Range: cellular organisms

Summary:
The degradation of carbohydrates from agricultural byproducts is a massive ecological and industrial management issue. Disaccharide degradation pathways involve the breakdown of the two monosaccharide units. Some examples include the sucrose degradation VII (sucrose 3-dehydrogenase), melibiose degradation, trehalose degradation II (trehalase), lactose degradation II and maltose degradation pathways.

Some microbes possess specialized disaccharide phophorylases that catalyze the transfer of a glycosyl moiety to a phosphate when a disaccharide is the donor substrate. Several disaccharide phosphorylases that catalyze the conversion of sucrose, trehalose, cellobiose etc have been extensively characterized.

Laminaribiose is a dissaccharide found in many agricultural plants. This pathway describes its phosphorolytic degradation by one such enzyme characterized from the unicellular flagellate protist Euglena gracilis [Dwyer70].
