Vajda V, Pucetaite M, McLoughlin S, Engdahl A, Heimdal J, Uvdal P
Nat Ecol Evol . 2017 Oct; 1(8):1093-1099. PMID: 29046567
Gene sequences form the primary basis for understanding the relationships among extant plant groups, but genetic data are unavailable from fossils to evaluate the affinities of extinct taxa. Here we...

Roger K, Liebi M, Heimdal J, Pham Q, Sparr E
Proc Natl Acad Sci U S A . 2016 Aug; 113(37):10275-80. PMID: 27573848
Water evaporation concerns all land-living organisms, as ambient air is dryer than their corresponding equilibrium humidity. Contrarily to plants, mammals are covered with a skin that not only hinders evaporation...

Zhu Q, Zheng K, Abdellah M, Generalov A, Haase D, Carlson S, et al.
Phys Chem Chem Phys . 2016 May; 18(22):14933-40. PMID: 27189431
After having emerged as primary contenders in the race for highly efficient optoelectronics materials, organolead halide perovskites (OHLP) are now being investigated in the nanoscale regime as promising building blocks...

Kaukonen M, Soderhjelm P, Heimdal J, Ryde U
J Chem Theory Comput . 2015 Dec; 4(6):985-1001. PMID: 26621239
Catalytic metal sites in enzymes frequently have second-sphere carboxylate groups that neutralize the charge of the site and share protons with first-sphere ligands. This gives rise to an ambiguity concerning...

Lindgren J, Sjovall P, Carney R, Cincotta A, Uvdal P, Hutcheson S, et al.
Sci Rep . 2015 Aug; 5:13520. PMID: 26311035
Feathers are amongst the most complex epidermal structures known, and they have a well-documented evolutionary trajectory across non-avian dinosaurs and basal birds. Moreover, melanosome-like microbodies preserved in association with fossil...

Lindgren J, Moyer A, Schweitzer M, Sjovall P, Uvdal P, Nilsson D, et al.
Proc Biol Sci . 2015 Aug; 282(1813):20150614. PMID: 26290071
Colour, derived primarily from melanin and/or carotenoid pigments, is integral to many aspects of behaviour in living vertebrates, including social signalling, sexual display and crypsis. Thus, identifying biochromes in extinct...

Nilsson E, Heimdal J, Bache-Andreassen L, Johnson M, Nielsen C
J Phys Chem A . 2015 Feb; 119(11):2562-7. PMID: 25654214
Acetaldehyde is a hazardous pollutant found in indoor and ambient air. Acetaldehyde photolysis is pressure- and wavelength-dependent with three distinct product channels. In this study, the photolysis rates of CH3CHO,...

Heimdal J, Ryde U
Phys Chem Chem Phys . 2012 Jul; 14(36):12592-604. PMID: 22797613
Lately, there has been great interest in performing free-energy perturbation (FEP) at the combined quantum mechanics and molecular mechanics (QM/MM) level, e.g. for enzyme reactions. Such calculations require extensive sampling...

Heimdal J, Kaukonen M, Srnec M, Rulisek L, Ryde U
Chemphyschem . 2011 Oct; 12(17):3337-47. PMID: 21960467
We used two theoretical methods to estimate reduction potentials and acidity constants in Mn superoxide dismutase (MnSOD), namely combined quantum mechanical and molecular mechanics (QM/MM) thermodynamic cycle perturbation (QTCP) and...

Hu L, Farrokhnia M, Heimdal J, Shleev S, Rulisek L, Ryde U
J Phys Chem B . 2011 Sep; 115(45):13111-26. PMID: 21955325
We have calculated the reorganization energy for the intramolecular electron transfer between the reduced type 1 copper site and the peroxy intermediate of the trinuclear cluster in the multicopper oxidase...
