1.2 C-1 kinases and sugar salvage pathways
Evidence that certain monosaccharides are hydrolyzed from polymeric forms during growth and development is implicit in the existence of C-1 kinases and NDP- pyrophosphorylases that return them directly to the nucleotide-sugar interconversion pathway. The monosaccharides capable of incorporation via these salvage pathways are: Galactose, GalA, Arabinose, Glucuronic acid, and Fucose. An arabinokinase was identified on the basis of a mutant (aral) sensitive to low amounts of arabinose, which is toxic.
