I. Yamato, ORDERED BINDING MODEL AS A GENERAL TIGHT COUPLING MECHANISM FOR BIOENERGY TRANSDUCTION - A HYPOTHESIS, Proceedings of the Japan Academy. Series B Physical and biological sciences, 69(8), 1993, pp. 218-223
The mechanism of secondary active transport processes has been propose
d as an ordered binding model, based on substrate binding studies depe
ndent on coupling cation concentrations (Yamato, I. (1992) FEBS Lett.,
298, 1-5). The reason why the systems adopt the ordered binding mecha
nism is discussed from the point of view of the coupling efficiency of
the energy transduction. It is proposed that the mechanism guarantees
the tight coupling of the system. The ordered binding mechanism is th
en proposed as the general mechanistic model for various bioenergy tra
nsducing systems with tight coupling.
