In the recently proposed local-access model for proton transfers in the bacteriorhodopsin transport cycle (Brown et al. 1998. Biochemistry. 37:3982–3993), connection between the retinal Schiff base and Asp⁸⁵ (in the extracellular direction) and Asp⁹⁶ (in the cytoplasmic direction) is maintained as long as the retinal is in its photoisomerized state. The directionality of the proton translocation is...

Biophysical Chemistry > 1997 > 67 > 1-3 > 1-25

This communication is devoted to the evaluation of true spectra and intrinsic (microscopic) rate constants from apparent kinetics measured in time-resolved spectroscopic experiments monitoring complex relaxation dynamics of multi-intermediate systems. Retinal proteins, cytochrom c oxidase, phytochrome, hemoglobin, and photoactive yellow protein are examples of natural systems in which several transient...

The photoinduced electric response of oriented purple membranes associated with processes before the K-intermediate decay of bacteriorhodopsin was measured in the 180–300 K temperature range. These response signals consist of two kinetically distinct components (both temperature dependent). The experimental data show a correlation between the time constants of the rise of the signal and solution resistance...
