form   lyophilized powder
storage temp.   2-8°C



Bacteriorhodopsin is of interest in the development of artificial retinas, optical associative processors, and three-dimensional memory storage devices.

The mutant D96N is useful for a wide range of data-storage and information processing applications, due the extended relaxation time.

Biochem/physiol Actions

A transmembrane retinylidine protein that functions as a proton pump driven by light energy in Holobacterium.

General description

Bacteriorhodopsin is the prototypical "seven-helix" transmembrane protein (with seven α-helical domains), whose study led to advances in understanding G protein-coupled receptors (GPCRs). In Halobacteria, it acts as a light-harvesting protein, producing a proton gradient across the cell wall that is then used to drive biosynthetic processes.

Preparation Note

Aqueous suspensions may be sonicated to achieve the desired homogeneity and may be stored for a short time at a temperature of 2-8 °C or at a temperature of -20 °C without time limitation.

Physical form

Isolated from Halobacterium salinarum sp. L33 as Purple Membranes
