Abstract:

Unspecific peroxygenase (EC 1.11.2.1) represents a group of secreted hemethiolate proteins that are capable of catalyzing the selective mono-oxygenation of diverse organic compounds using only H2O2 as a cosubstrate. In this study, the peroxygenase from Agrocybe aegerita (AaeUPO) was found to catalyze the hydroxylation of various linear (e.g n-hexane), branched (e.g. 2,3-dimethylbutane) and cyclic alkanes (e.g. cyclohexane). The size of n-alkane substrates converted by AaeUPO ranged from gaseous propane (C3) to n-hexadecane (C16). They were mono-hydroxylated mainly at the C2 and C3 position, ra

Abstract:

Bacterial monooxygenases have important roles in the biogeochemical cycling of carbon and nitrogen, as well as potential applications in biocatalysis of pharmaceutically important epoxides, and bioremediation of chlorinated pollutants. However, use of monooxygenases for biotechnology requires understanding of microbial physiology and the catalytic properties (e.g. substrate range and kinetic parameters) of monooxygenases themselves. Heterologous expression of monooxygenases is one way to advance our fundamental knowledge of MO functions, and also to enable future applications. This project f

Abstract:

The functionalization of hydrocarbons in a sustainable manner is one of the main challenges for chemists. Their abundance in nature as natural gas or crude oil makes them the most convenient chemical feedstock. The oxidation of hydrocarbons is one of the most interesting reactions, because the introduction of an oxygen atom introduces functionality in these molecules, increasing their value as reagents for further chemical transformation. However, these reactions are fundamentally difficult due to the low reactivity of alkyl C-H bonds. Current available methodologies involve highly reactive-ox

Biomass is a renewable source of energy and represents an acceptable alternative to fosil fuels. Usable methods of energetic use of biomass are combustion and gasification. Main interest is focused on gasification in last years. Gasification is based on conversion of organic material to usable gaseous product called syngas, which can be used as a fuel for energy production. Large amount of tar is formed as a by-product of incineration and gasification of biomass. Tar is composed by various mixture of organic substances, has a negative effect on operating conditions and is a potential threat to

Bioorthogonal reactions, due to its excellent selectivity and time-efficiency, have emerged as a popular tool for protein and cell probing. Among all the bioorthogonal reactions, the inverse electron-demand Diels-Alder reaction (IEDDA) reaction has its advantage of bearing the fastest kinetics. Although the IEDDA reaction drew considerable attention in chemical biology in the last decade, challenges lie in finding the suitable dienophiles. Strained dienophiles, for example, trans-cyclooctene derivatives, can undergo ultrafast IEDDA reactions and therefore have been extensively developed. Unstr

Abstract:

Nitrogen-containing molecules are ubiquitous in both natural products and pharmaceutical drugs, thus an efficient method for the formation of these motifs is of great importance. Hydroamination, that is the addition of an N-H bond across an unsaturated carbon-carbon bond of an alkene or alkyne, stands out as a potential approach to obtain such molecules. To date, most research in this area relies on transition-metal catalysis to enable such reactivity. In efforts directed towards metal-free alternatives, we have developed a simple, metal-free hydroamination of alkenes using hydrazides. Fur

Abstract:

The oxidative dehydrogenation (ODH) of n-octane to produce octene at atmospheric pressure has been studied using an industrially supplied iron molybdate catalyst from Johnson Matthey (JM). In situ X-ray diffraction studies revealed at temperatures ≥450 °C the catalyst undergoes a reductive phase transition when reacted with noctane at 450 °C where the phase changes from Fe2(MoO4)3-MoO3 to FeMoO4-MoO2-Mo4O11. As a result, if the temperature is taken back below this point the catalyst does not revert to the original phase and therefore the same activity and selectivity cannot be achieved.
