Abstract
The ability of Lactobacillus plantarum NC2 to transport thiomethyl-beta-d-galactoside in the presence or absence of various inhibitors was investigated to determine the mechanism of beta-galactoside transport in this bacterium. A novel system employing l-arabinose as an energy-generating compound is described, and evidence that this transport is energized by an ATP-driven proton motive force is presented.
摘要
研究了植物乳杆菌NC2在存在或不存在各种抑制剂的情况下转运硫代甲基-β-D-半乳糖苷的能力，以确定该细菌中β-半乳糖苷转运的机制。描述了一种使用L-阿拉伯糖作为能量产生化合物的新系统，并提供了证据表明这种转运是由ATP驱动的质子动力提供能量的。
