Evidence of the active transport of carbohydrates by acholeplasma laidlawii membrane vesicles


, : Evidence of the active transport of carbohydrates by acholeplasma laidlawii membrane vesicles. Biofizika 22(2): 276-280

A. laidlawii membrane vesicles can accumulate 14C-glucose, maltose and fructose against the concentration gradient in the absence of exogenous energy sources. Sugar transport is inhibited by anaerobiosis and by electron transport inhibitors such as rotenone and amytal, and by proton conductors such as carbonylcyanide-m-chlorophenylhydrazone. Arsenate and dicyclohexylcarbodiimide (inhibitor of membrane-bound ATPase) do not inhibit the sugar transport. Apparently, sugar transport in the membrane vesicles can be driven by the high-energy state of the membrane or the membrane potential.
