Structural basis of L

For about 70 years L-glucose had been considered non-metabolizable by either mammalian or bacterial cells Recently however an L-glucose catabolic pathway has been discovered in Paracoccus laeviglucosivorans and the genes responsible cloned Scyllo-inositol dehydrogenase is involved in the first step in the pathway that oxidizes L-glucose to produce L-glucono-1 5-lactone with concomitant
