2-deoxy-D-lyxo-hexose
Notes:
2-Deoxygalactopyranose is an optical isomer of 2-deoxyglucose, which has the 2-hydroxyl group replaced by hydrogen. 2-deoxygalactose inhibits galactose uptake and oxidation in galactose-grown cells. Similar to galactose,
2-deoxyglucose, and D-fucose, 2-deoxygalactose induces uptake of H+ when the sugar is added to anaerobic wild-type cells that contain the galactose transport system, whereas the maximal rate of uptake is one-half to one-third of that of galactose. 2-Deoxygalactose is a specific substrate of the galactose permease. None of the other galactose transport systems, including methyl beta-D-thiogalactosides I and II, the beta-methyl-galactoside permease, and both arabinose systems, is able to catalyze transport of 2-deoxygalactose to a significant extent. 2-Deoxygalactose can also be used to isolate mutants defective in galactose permease, since it is bacteriostatic.
