Lactose monohydrate is a type of sugar found in milk. Due to its chemical structure, it’s processed into a powder and used as a sweetener, stabilizer, or filler in the food and pharmaceutical ...

Kaback and his colleagues recently captured the three-dimensional structure of lactose permease (LacY), which moves lactose across the cell membrane of E. coli, a common bacterium.

Lactose is a disaccharide, meaning it is composed of two types of simpler sugars, glucose and galactose, that are bound together. These form long chains, or polymers, in food. But the unique structure ...

For example, the general structure of lactose repressor has been known for some time, but questions have remained about how it flexes and moves inside a living cell.

UCLA physiologist H. Ronald Kaback recently solved the three-dimensional structure of lactose permease (LacY), which moves lactose across the cell membrane of E. coli.

Lactose permease (LacY) of Escherichia coli stands as a prototype of the major facilitator superfamily, employing the energy of a proton gradient to mediate the uptake of sugars against their ...
