General Information

General Information Comment Organism
metabolism members from the order Bifidobacteriales differ from all other organisms in using a unique pathway for carbohydrate metabolism, known as the "bifid shunt", which utilizes the enzyme phosphoketolase to carry out the phosphorolysis of both fructose-6-phosphate and xylulose-5-phosphate. The existence of the bifid shunt allows bifidobacteria to produce more ATP from carbohydrates than through other conventional pathways. In contrast to bifidobacteria, the phosphoketolases found in other organisms (referred to XPK) are able to metabolize primarily xylulose-5-phosphate and show very little activity towards fructose-6-phosphate Bifidobacterium longum
