Biochemical evidence for the presence of two alpha-glucoside ABC-transport systems in the hyperthermophilic archaeon Pyrococcus furiosus

Archaea. 2002 Mar;1(1):19-25. doi: 10.1155/2002/529610.

Abstract

The hyperthermophilic archaeon Pyrococcus furiosus can utilize different carbohydrates, such as starch, maltose and trehalose. Uptake of alpha-glucosides is mediated by two different, binding protein-dependent, ATP-binding cassette (ABC)-type transport systems. The maltose transporter also transports trehalose, whereas the maltodextrin transport system mediates the uptake of maltotriose and higher malto-oligosaccharides, but not maltose. Both transport systems are induced during growth on their respective substrates.
