Example sentencesExamples
- The membrane protein bacteriorhodopsin, a light-driven proton pump, is a very suitable protein to study proton transfer.

- Internal structural water molecules seem to play an important role in proton conduction in membrane proteins like bacteriorhodopsin, the photosynthetic reaction center, and cytochrome-c oxydases.
- Even native, isolated pigment proteins like bacteriorhodopsin have been investigated for their applicability as optical switches.
