Metabolite Identification
Common NameL-Rhamnulose
DescriptionL-Rhamnulose is a breakdown product of L-rhamnose, which is ubiquitous and particularly abundant in some plants, such as buckthorn. Rhamnose is also one of the sugars regularly used to conduct the dual sugar permeability test. Rhamnose is fermented by some colonic bacteria into L-rhamnulose. Three bacterial (gut micrflora) enzymes are involved in Rhamnose degradation including rhaB (rhamulose kinase), rhaA (rhamnose isomerase), and rhaD (rhamnulose-1-phosphate aldolase). L-rhamnulose kinase catalyzes the transfer of the gamma-phosphate group from ATP to the 1-hydroxyl group of L-rhamnulose. E.coli are growing depending on L-rhamnose as a source of carbon and energy.
