Developments in computational chemistry, bioinformatics, and laboratory evolution have facilitated the de novo design and catalytic optimization of enzymes. Besides creating useful catalysts, the generation and iterative improvement of designed enzymes can provide valuable insight into the interplay between the many phenomena that have been suggested to contribute to catalysis. In this work, we fo

We investigated whether local biotic and abiotic conditions could explain the occurrence of calling males of the declining spadefoot toad Pelobates fuscus in 72 ponds in southern Sweden. The ponds covered the entire distribution range of P. fuscus and were monitored during the breeding season in 2000. Calling males were found in 33 ponds. representing ca 50% of all known ponds for the species ill

Popular Abstract in Swedish Cellulosa är ett av de vanligast förekommande biologiska ämnena på jorden och en mycket viktig råvara. Cellulosa är en polymer, uppbyggd av glukosmolekyler som är bundna till varandra i kedjor. Kedjorna kan bli mycket långa och består ofta av flera tusen glukosmolekyler. Eftersom cellulosakedjor är lineära kan de packa sig parallellt med varandra och bilda styva fibrer Soluble derivatives of cellulose have become increasingly important in industrial products e.g. in pharmaceutical applications and in technical dispersions. The polymer characteristics of modified celluloses are to a high degree determined by the substituent distribution along the polymeric backbone. The distribution will be more or less heterogeneous both due to the fact that polymers from renewa

Abstract in French La morphologie verbale de personne-nombre se développe lentement chez les apprenants adultes (suédophones) de français L2. Ce développement, chez eux, ne semble pas relié au développement syntaxique, mais possiblement à des facteurs de fréquence de ces formes dans l’input. On ne peut pas non plus considérer les pronoms sujets chez ces apprenants comme des marqueurs de personne (

Human complement component C4 was irreversibly inactivated by low concentrations of methylamine at slightly alkaline pH. The inactivated C4 molecules lost the ability to bind to EAC1 cells but retained th capacity to participate in the formation of classical pathway C3 convertase in the fluid phase. 14C-methylamine was incorporated into the alpha-chain at a ratio of 1 mol methylamine per mol C4.

Monosubstituted naphthoxylosides have been shown to function as substrates for, and inhibitors of, the enzyme β4GalT7, a key enzyme in the biosynthetic pathway leading to glycosaminoglycans and proteoglycans. In this article, we explore the synthesis of 16 xyloside analogues, modified at two different positions, as well as their function as inhibitors of and/or substrates for the enzyme. Seemingly
