A Triplet Label Extends Two‐Dimensional Infrared Spectroscopy from Pico‐ to Microseconds

Autor: Hendrik Brunst, Hafiz M. A. Masood, A. Rafael Thun, Alexander Kondratiev, Georg Wille, Luuk J. G. W. van Wilderen, Jens Bredenbeck

Publikováno v: Angewandte Chemie International Edition. 61

In conventional two-dimensional infrared (2D-IR) spectroscopy, the inherently short vibrational lifetimes limit the time window to observe molecular dynamics typically to tens of picoseconds. The rather complex dynamics of organized molecular systems

Infrared pre-excitation grants isotopomer-specific photochemistry

Autor: Kern-Michler Daniela, Neumann Carsten, Mielke Nicole, Luuk J. G. W. van Wilderen, Reinfelds Matiss, von Cosel Jan, Santoro Fabrizio, Heckel Alexander, Burghardt Irene, Bredenbeck Jens

Publikováno v: EPJ Web of Conferences, Vol 205, p 03001 (2019)

Species-selective photochemistry is often hampered by overlapping UV-Vis spectra. We overcome this long-standing problem by combined vibrational and electronic excitation as demonstrated by isotopomer selection. The influence of various factors on se

Vibrational Lifetime of the SCN Protein Label in H2O and D2O Reports Site-Specific Solvation and Structure Changes During PYP’s Photocycle

Autor: Julian M. Schmidt-Engler, Luuk J. G. W. van Wilderen, Bartosz Błasiak, Jens Bredenbeck, Minhaeng Cho, Larissa Blankenburg

Publikováno v: Analytical Chemistry. 92:1024-1032

The application of vibrational labels such as thiocyanate (-S-C≡N) for studying protein structure and dynamics is thriving. Absorption spectroscopy is usually employed to obtain wavenumber and line shape of the label. An observable of great signifi

Amide I difference spectroscopy is widely used to investigate protein function and structure changes. In this article, we show that the common approach of assigning features in amide I difference signals to distinct secondary structure elements in ma

Femtosecond-to-millisecond mid-IR spectroscopy of photoactive yellow protein uncovers structural micro-transitions of the chromophore’s protonation mechanism

Autor: Luuk J. G. W. van Wilderen, Larissa Blankenburg, Jens Bredenbeck

Publikováno v: The Journal of Chemical Physics. 156:205103

Protein structural dynamics can span many orders of magnitude in time. Photoactive yellow protein’s (PYP) reversible photocycle encompasses picosecond isomerization of the light-absorbing chromophore as well as large scale protein backbone motions
