The Osteoclast as a Unicellular Proton-Transporting Epithelium

The American Journal of the Medical Sciences, 1992
Osteoclasts dissolve bone mineral by the vectorial secretion of hydrogen ion at their osseous attachment site. To accomplish this, the osteoclast employs a vacuolar H+ ATPase that is polarized to the specialized proton-secreting plasma membrane domain, the ruffled border. Physiologically and biochemically, they resemble the specialized proton-secreting

Fundamental Features of Proton-Coupled Transport

Biochemical Society Transactions, 1977
I must make clear the distinctions between my approach (Williams, 1961) and that of Mitchell (1961) (chemiosmosis) to proton-energized transport across membranes. Initially these have many reactions in common which are not osmotic in character: (1) Light or oxidation energy produces a charge gradient in the membrane.

Proton Dynamics in Light-Driven Proton Transporters

Mikrobielle Rhodopsine sind Retinal-bindende, membrandurchspannende Photorezeptoren, die vielfältige zelluläre Funktionen, darunter Ionentransport, Photosensorik und enzymatische Aktivität vermitteln. In dieser Dissertation werden drei verschiedene Protonen transportierende Rhodopsine untersucht: UmRh1 aus einem pflanzenpathogenen Pilz (nach außen ...

[1] Energetics of proton transport and secondary transport

1986
Publisher Summary This chapter discusses energetics of proton transport and secondary transport. Proton pumps and their associated proton-coupled transport systems are the most common biological systems of energy conversion. In describing the energetics of these systems, it is useful to distinguish between primary active transport systems or pumps ...
