Ernst HA, Wolf TJ, Schalk O, González-García N, Boguslavskiy AE, Stolow A, Olzmann M, Unterreiner AN.
PMID: 26266823
J Phys Chem A. 2015 Sep 03;119(35):9225-35. doi: 10.1021/acs.jpca.5b04900. Epub 2015 Aug 22.

The photolysis of o-nitrophenol (o-NP), a typical push-pull molecule, is of current interest in atmospheric chemistry as a possible source of nitrous acid (HONO). To characterize the largely unknown photolysis mechanism, the dynamics of the lowest lying excited singlet...

Chemphyschem. 2008 Dec 22;9(18):2731-6. doi: 10.1002/cphc.200800571.

We study aqueous solutions of alkaline chlorides (NaCl, KCl, RbCl and CsCl) with a combination of attenuated total reflection infrared (ATR-IR) spectroscopy and molecular dynamics (MD) simulations using the TIP4P-Ew water model (Horn et al., J. Chem. Phys. 2004,...

Accurate computational determination of the binding energy of the SO3 x H2O complex.

The Journal of chemical physics

Fliegl H, Glöss A, Welz O, Olzmann M, Klopper W.
PMID: 16942218
J Chem Phys. 2006 Aug 07;125(5):054312. doi: 10.1063/1.2234372.

Reliable thermochemical data for the reaction SO3 + H2OSO3 x H2O (1a) are of crucial importance for an adequate modeling of the homogeneous H2SO4 formation in the atmosphere. We report on high-level quantum chemical calculations to predict the binding...

Shock-tube study of the thermal decomposition of CH3CHO and CH3CHO + H reaction.

Bentz T, Striebel F, Olzmann M.
PMID: 18547039
J Phys Chem A. 2008 Jul 10;112(27):6120-4. doi: 10.1021/jp802030z. Epub 2008 Jun 12.

The thermal decomposition of acetaldehyde, CH3CHO + M --> CH3 + HCO + M (eq 1), and the reaction CH3CHO + H --> products (eq 6) have been studied behind reflected shock waves with argon as the bath gas...

Kinetics of the NCN + NO reaction over a broad temperature and pressure range.

The journal of physical chemistry. A

Welz O, Olzmann M.
PMID: 22694482
J Phys Chem A. 2012 Jul 12;116(27):7293-301. doi: 10.1021/jp303069g. Epub 2012 Jul 03.

Rate coefficients for the reaction (3)NCN + NO → products (R3) were measured in the temperature range 251-487 K at pressures from 10 mbar up to 50 bar with helium as the bath gas. The experiments were carried out...

Reaction of dimethyl ether with hydroxyl radicals: kinetic isotope effect and prereactive complex formation.

The journal of physical chemistry. A

Bänsch C, Kiecherer J, Szöri M, Olzmann M.
PMID: 23914942

The kinetic isotope effect of the reactions OH + CH3OCH3 (DME) and OH + CD3OCD3 (DME-d6) was experimentally and theoretically studied. Experiments were carried out in a slow-flow reactor at pressures between 5 and 21 bar (helium as bath...

Native mass spectrometry combined with enzymatic dissection unravels glycoform heterogeneity of biopharmaceuticals.

Nature communications

Wohlschlager T, Scheffler K, Forstenlehner IC, Skala W, Senn S, Damoc E, Holzmann J, Huber CG.
PMID: 29712889
Nat Commun. 2018 Apr 30;9(1):1713. doi: 10.1038/s41467-018-04061-7.

Robust manufacturing processes resulting in consistent glycosylation are critical for the efficacy and safety of biopharmaceuticals. Information on glycosylation can be obtained by conventional bottom-up methods but is often limited to the glycan or glycopeptide level. Here, we apply...

The enzymes glyoxalase 1 and 2 (Glo1 and Glo2) are found in most eukaryotes and catalyze the glutathione-dependent conversion of 2-oxoaldehydes to 2-hydroxycarboxylic acids. Four glyoxalases are encoded in the genome of the malaria parasite

Ending on a sour note: Lipids orchestrate ferroptosis in cancer.

Cell metabolism

Lange M, Olzmann JA.
PMID: 34348094
Cell Metab. 2021 Aug 03;33(8):1507-1509. doi: 10.1016/j.cmet.2021.07.011.

Lipid metabolism is altered in the acidic tumor microenvironment. Here, the authors show that polyunsaturated fatty acid supplementation, together with concomitant inhibition of lipid droplet biogenesis, induces ferroptosis in acidic cancer cells. These findings highlight the potential to exploit...
