Redox active cysteine residues including βCys93 are part of hemoglobin's “oxidation hotspot”. Irreversible oxidation of βCys93 ultimately leads to the collapse of the hemoglobin structure and release of heme. Human fetal hemoglobin (HbF), similarly to the adult hemoglobin (HbA), carries redox active γCys93 in the vicinity of the heme pocket. Site-directed mutagenesis has been used in this study to

We have used density functional methods to calculate fully relaxed potential energy curves of the seven lowest electronic states during the binding of O-2 to a realistic model of ferrous deoxyheme. Beyond a Fe-O distance of similar to 2.5 Angstrom, we find a broad crossing region with five electronic states within 15 kJ/mol. The almost parallel surfaces strongly facilitate spin inversion, which is

The bifunctional dCTP deaminase-dUTPase (DCD-DUT) from Methanocaldococcus jannaschii catalyzes the deamination of the cytosine moiety in dCTP and the hydrolysis of the triphosphate moiety forming dUMP, thereby preventing uracil from being incorporated into DNA. The crystal structure of DCD-DUT has been determined to 1.88-Å resolution and represents the first known structure of an enzyme catalyzing

Lattice Boltzmann method (LBM) is an alternative to conventional CFD to capture the detailed activities of the transport processes at microscale. Here LBM is used to model the hydrogen production by splitting water by incident sunlight over water covered Si-nanorods. The purpose of this study is, by a 3D microscale model, to investigate the transport and the formation of the hydrogen bubbles by el

Online wall temperatures were measured with fiber-coupled phosphor thermometry in a full-scale gas turbine combustor. The combustor was operated with natural gas and up to 100 vol% hydrogen at engine-relevant conditions. Two phosphors were tested for this application, namely YAG:Dy and YAG:Tm;Li. Although YAG:Tm;Li seemed to be the most promising phosphor for this application, it turned out to be

One of the biggest obstacles to economic profitability of solar water heating systems is the investment cost. Retrofitting existing domestic hot water heaters when a new solar hot water system is installed can reduce both the installation and material costs. In this study, retrofitting existing water heaters for solar water heating systems in Swedish single-family houses was theoretically investig

Using spectra of RR Lyrae stars in the Small Magellanic Cloud (SMC) a metallicity snapshot from an early epoch in the history of the SMC could possibly be obtained. The SMC, one of our closest neighbours in the Local Group of galaxies, offers the opportunity to study another galaxy close-up. The history of the SMC can be traced using the chemical characteristics of its different generations of sta

Since the liberalisation of the Swedish electricity market in 1996, the competition between utilities has increased, and the generation capacity has gradually been adjusted to suit the demand. Consequently, the earlier excessive electricity production capacity has been reduced. However, if the gap between the generation capacity and demand will be too narrow, this may result in notable power short

Popular Abstract in Swedish Hemoglobin, det protein som transporterar syre i blodet är förmodligen det mest välkända proteinet. Det är ett av många exempel på porfyrinproteiner, dvs. proteiner med en porfyrinring i det aktiva centrat. Porfyrinen kan binda en metalljon i mitten av ringen. När en järnjon är bunden kallas strukturen hem. Det är denna molekyl som finns i hemoglobin. I denna avhandling

MAX IV is presently under construction at Lund, Sweden, and the first beam for the production of synchrotron radiation is expected to circulate in 2016. The whole set of 3 GeV ring beam pipes is coated with Ti-Zr-V Non Evaporable Getter (NEG) thin film in order to fulfil the average pressure requirement of 1×10-9 mbar, despite the compact magnet layout and the large aspect ratio of the vacuum cham

A simplified description and a corresponding force field for polypeptides is introduced. Each amino acid residue is reduced to one interaction site, representing the backbone, and one or two side chain sites depending on its size and complexity. Site–site interactions are parameterized after a hydrophobicity criterium. The treatment of backbone sites is in addition designed to reproduce typical po

The total of catalytic particles is often unavailable to participate in the electrochemical reactions in a PEFC, which limits the PEFC performance. The electrochemical surface area (ECSA) becomes an important metric to diagnose the catalyst layer's performance and evaluate the development of new electrode materials to achieve better overall efficiency. This work intends to analyze the effects of a

Climate change, energy security and air pollution are all motivators for the further development of fuel cells. A volume of fluid approach was used to investigate the impact of dynamic contact angle boundary conditions (Kistler model), mainly at the gas diffusion layer surface but also at the channel wall, of a polymer electrolyte fuel cell gas channel. From this study, it is clear that a dynamic
