Time-resolved visible and infrared absorption spectroscopy data obtained using photosystem I particles with non-native quinones incorporated into the A1 binding site.

ABSTRACT: Time-resolved visible and infrared absorption difference spectroscopy data at both 298 and 77 K were obtained using cyanobacterial menB (-) mutant photosystem I particles with several non-native quinones incorporated into the A1 binding site. Data was obtained for photosystem I particles with phylloquinone (2-methyl-3-phytyl-1,4-naphthoquinone), 2-bromo-1,4-naphthoquinone, 2-chloro-1,4-naphthoquinone, 2-methyl-1,4-naphthoquinone, 2,3-dibromo-1,4-naphthoquinone, 2,3-dichloro-1,4-naphthoquinone, and 9,10-anthraquinone incorporated. Transient absorption data were obtained at 487 and 703 nm in the visible spectral range, and 1950-1100 cm(-1) in the infrared region. Time constants obtained from fitting the time-resolved infrared and visible data are in good agreement. The measured time constants are crucial for the development of appropriate kinetic models that can describe electron transfer processes in photosystem I, "Modeling Electron Transfer in Photosystem I" Makita and Hastings (2016) [1].

Project description:A phylloquinone molecule (2-methyl, 3-phytyl, 1, 4-naphthoquinone) occupies the A(1) binding site in photosystem 1 particles from Synechocystis sp. 6803. In menB mutant photosystem 1 particles from the same species, plastoquinone-9 occupies the A(1) binding site. By incubation of menB mutant photosystem 1 particles in the presence of phylloquinone, it was shown in another study that phylloquinone will displace plastoquinone-9 in the A(1) binding site. We describe the reconstitution of unlabeled ((16)O) and (18)O-labeled phylloquinone back into the A(1) binding site in menB photosystem 1 particles. We then produce time-resolved A(1)(-)/A(1) Fourier transform infrared (FTIR) difference spectra for these menB photosystem 1 particles that contain unlabeled and (18)O-labeled phylloquinone. By specifically labeling only the phylloquinone oxygen atoms we are able to identify bands in A(1)(-)/A(1) FTIR difference spectra that are due to the carbonyl (C=O) modes of neutral and reduced phylloquinone. A positive band at 1494 cm(-1) in the A(1)(-)/A(1) FTIR difference spectrum is found to downshift 14 cm(-1) and decreases in intensity on (18)O labeling. Vibrational mode frequency calculations predict that an antisymmetric vibration of both C=O groups of the phylloquinone anion should display exactly this behavior. In addition, phylloquinone that has asymmetrically hydrogen bonded carbonyl groups is also predicted to display this behavior. The positive band at 1494 cm(-1) in the A(1)(-)/A(1) FTIR difference spectrum is therefore due to the antisymmetric vibration of both C=O groups of one electron reduced phylloquinone. Part of a negative band at 1654 cm(-1) in the A(1)(-)/A(1) FTIR difference spectrum downshifts 28 cm(-1) on (18)O labeling. Again, vibrational mode frequency calculations predict this behavior for a C=O mode of neutral phylloquinone. The negative band at 1654 cm(-1) in the A(1)(-)/A(1) FTIR difference spectrum is therefore due to a C=O mode of neutral phylloquinone. More specifically, calculations on a phylloquinone model molecule with the C(4)=O group hydrogen bonded predict that the 1654 cm(-1) band is due to the non hydrogen bonded C(1)=O mode of neutral phylloquinone.

Project description:Attenuated total reflection surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS) is a powerful method for probing interfacial chemical processes. However, SEIRAS-active nanostructured metallic thin films for the in situ analysis of electrochemical phenomena are often unstable under biased aqueous conditions. In this work, we present a surface-enhancing structure based on etched black Si internal reflection elements with Au-coatings for in situ electrochemical ATR-SEIRAS. Using electrochemical potential-dependent adsorption and desorption of 4-methoxypyridine on Au, we demonstrate that black Si-based substrates offer advantages over commonly used structures, such as electroless-deposited Au on Si and electrodeposited Au on ITO-coated Si, due to the combination of high stability, sensitivity, and conductivity. These characteristics are especially valuable for time-resolved measurements where stable substrates are required over extended times. Furthermore, the low sheet resistance of Au layers on black Si reduces the RC time constant of the electrochemical cell, enabling a significantly higher time resolution compared to that of traditional substrates. Thus, we employ black Si-based substrates in conjunction with rapid- and step-scan Fourier transform infrared (FTIR) spectroscopy to investigate the adsorption and desorption kinetics of 4-methoxypyridine during in situ electrochemical potential steps. Adsorption is shown to be diffusion-limited, which allows for the determination of the mean molecular area in a fully established monolayer. Moreover, no significant changes in the peak ratios of vibrational modes with different orientations relative to the molecular axis are observed, suggesting a single adsorption mode and no alteration of the average molecular orientation during the adsorption process. Overall, this study highlights the enhanced performance of black Si-based substrates for both steady-state and time-resolved in situ electrochemical ATR-SEIRAS, providing a powerful platform for kinetic and mechanistic investigations of electrochemical interfaces.
