Our research about Competing Dispersive Interactions accepted in JPCL

Modern structural studies of biologically relevant molecules require an exhaustive interplay between experiment and theory. In this work, we present two examples where a poor choice of the theoretical method led to a misinterpretation of experimental results. We do that by performing a rotational spectroscopy study on two large and flexible biomolecules: methyl jasmonate and zingerone. The results show the enormous potential of rotational spectroscopy as a benchmark to evaluate the performance of theoretical methods.

The investigation has been published in JPCL

Aran Insausti talks in the 25th International Conferences on High-Resolution Molecular Spectroscopy

Aran Insausti presented the experimental and theoretical study of the Tn antigens in the gas, solution and solid phases that has been applied to deduce the key role of water in the modulation of the conformational preferences of these molecules and therefore in their presentations for interacting with protein receptors.

Conferences on High-Resolution Molecular Spectroscopy

The 2018 Edition of the Prague Series of International Conferences on High-Resolution Molecular Spectroscopy was held in Bilbao (Spain) this September 3-7.
We presented recent results focused on solving various structural problems of Chemistry at the molecular level. In particular, the conformational landscape of large clusters and biomolecules, including sugars, glycopeptides and drugs have been studied by our group recently.

Our research about the Tumor-Associated Carbohydrate Tn Antigens spotlight in JACS

We report that two seemingly similar variants of Tn antigens have very different conformations in water. Using interdisciplinary approaches, both experimental and computational, the team showed that the threonine-linked Tn antigen assumes a rigid form in solution and forms a persistent water pocket. In contrast, the serine-linked Tn antigen lacks the water pocket and is flexible in solution. These differences were not observed in gas phase studies.
The different Tn antigen conformations are likely to result in distinct interactions with cellular receptors and antibodies and understanding these structures may facilitate the design of more effective screening tools and anticancer drugs.

Emilio J. Cocinero gives a talk in Kaiserslautern, Germany

Emilio J. Cocinero was invited by Markus Gerhards to Kaiserslautern, Germany, where he presented several studies on biomolecules (carbohydrates and glycopeptides) and several applications, exploiting an experimental strategy which combines microwave and laser spectroscopies in high resolution, computation and synthesis. In addition, other applications of high resolution spectroscopies were presented.

Shapes, Dynamics, and Stability of β Ionone and Its Two Mutants

We report the potential of state-of-the-art rotational technique (recently built at the University of the Basque Country) with an extended molecular analysis of three biomolecules combined to quantum chemical calculations and crystallized data comparison.

The results are impressive: more than 8000 transitions have been assigned, corresponding to the rotational structures of 54 different species (3 molecules, 14 conformers and 40 isotopologues). In addition, methyl internal rotation dynamics were also observed and analyzed.

The investigation is being published in J. Phys. Chem. Lett.
