Hydroxide Ion Mechanism for Long-Range Proton Pumping in the Third Proton Transfer of Bacteriorhodopsin.
Ono J, Okada C, Nakai H. Ono J, et al. Chemphyschem. 2022 Nov 18;23(22):e202200109. doi: 10.1002/cphc.202200109. Epub 2022 Aug 23. Chemphyschem. 2022. PMID: 35818319
The free energy analysis confirms that the path via hydroxide ions is considerably favorable and consistent with the observed lifetime of the transient water wire. Therefore, the proposed hydroxide ion mechanism, as in the first proton transfer, is responsible for t …

Hydroxide Ion Carrier for Proton Pumps in Bacteriorhodopsin: Primary Proton Transfer.
Ono J, Imai M, Nishimura Y, Nakai H. Ono J, et al. J Phys Chem B. 2020 Oct 1;124(39):8524-8539. doi: 10.1021/acs.jpcb.0c05507. Epub 2020 Sep 17. J Phys Chem B. 2020. PMID: 32877195
The simulations showed a novel proton transfer mechanism, viz. the hydroxide ion mechanism, in which the deprotonation of specific internal water (Wat452) yields the protonation of Asp85 via Thr89, after which the resulting hydroxide ion accepts the re …

Translational Jump-Diffusion of Hydroxide Ion in Anion Exchange Membrane: Deciphering the Nature of Vehicular Diffusion.
Dubey V, Daschakraborty S. Dubey V, et al. J Phys Chem B. 2022 Mar 31;126(12):2430-2440. doi: 10.1021/acs.jpcb.2c00240. Epub 2022 Mar 16. J Phys Chem B. 2022. PMID: 35294202
To answer this question, we perform a classical molecular dynamics simulation of a system containing a hydroxide ion exchange membrane polymer and hydroxide ion at different hydration levels and temperatures using the same molecular force field (Dubey, …

The role of the chemical burns caused by hydroxide ion in the toxicity of dermal exposure to tetramethylammonium ion in a rat model.
Wu CL, Su SB, Lien HY, Guo HR. Wu CL, et al. Burns. 2012 Nov;38(7):1051-7. doi: 10.1016/j.burns.2012.02.027. Epub 2012 Jun 13. Burns. 2012. PMID: 22698842
OBJECTIVE: To evaluate the role of the chemical burns caused by hydroxide ion in the fatal effects of tetramethylammonium ion (TMA) in dermal exposure to tetramethylammonium hydroxide (TMAH), we conducted a rat study consisting of two-step treatments with dermal exp …

Hydroxide ion can move faster than an excess proton through one-dimensional water chains in hydrophobic narrow pores.
Bankura A, Chandra A. Bankura A, et al. J Phys Chem B. 2012 Aug 16;116(32):9744-57. doi: 10.1021/jp301466e. Epub 2012 Aug 7. J Phys Chem B. 2012. PMID: 22793519
This faster migration of the hydroxide ion is found not only in CNTs with periodicity along the tube axis but also in isolated CNTs where the excess proton and the hydroxide ion are allowed to move under the influence of an electric field of an opposit …

Excited-state hydroxide ion transfer from a model xanthenol photobase.
Xie Y, Luk HL, Yang X, Glusac KD. Xie Y, et al. J Phys Chem B. 2015 Feb 12;119(6):2498-506. doi: 10.1021/jp5080169. Epub 2014 Nov 11. J Phys Chem B. 2015. PMID: 25347397
This article reports a study of excited-state hydroxide ion release from a model xanthenol photobase, XanOH. The driving force for the reaction was tuned using solvent mixtures with varying water/acetonitrile ratios, and the kinetics of the reaction was monitored us …
