摘要
Halophilic archaea (haloarchaea) inhabit hypersaline environments,tolerating extreme salinity,low oxygen and nutrient availability,and in some cases,high pH (soda lakes) and irradiation (saltern ponds).Membrane-associated proteins of haloarchaea,such as surface layer (S-layer) proteins,transporters,retinal proteins,and internal organellar membrane proteins including intracellular gas vesicle proteins and those associated with polyhydroxyalkanoate (PHA) granules,contribute greatly to their environmental adaptations.This review focuses on these haloarchaeal cellular and organellar membrane-associated proteins,and provides insight into their physiological significance and biotechnological potential.

Membrane-associated proteins of haloarchaea, such as surface layer (S-layer) proteins, transporters, retinal proteins, and internal organellar membrane proteins including in- tracellular gas vesicle proteins and those associated with polyhydroxyalkanoate (PHA) granules, contribute greatly to their en- vironmental adaptations. This review focuses on these haloarchaeal cellular and organellar membrane-associated proteins, and provides insight into their physiological significance and biotechnological potential.
