Transaminases have arisen as one of the main biocatalysts for amine production but despite their many advantages, stability is still a concern widespread application. One reasons instability need to use an excess amino donor when trying synthesise amines with unfavourable equilibria. To circumvent this, recycling systems donor, such acid dehydrogenases or aldolases, proved useful push equilibri...

BACKGROUND Sodium/proton-antiporters (Nha) are known to play an important role in pH- and Na+-homeostasis. In microorganisms several types with different capacity, affinity and selectivity for Na+ and Li+ exist. The homeostasis system of E. coli, NhaA and NhaB, is well researched, but the function of other types of Na+/H+-antiporters like NhaD is yet to be fully understood. Since several antipo...

A new family, the Hafomonadaceae, has recently been proposed for members of the genera Deleya and Halornonas. The three strains investigated, Deleya haiuphila, Halomonas elongata and Flavobacterium halmephilum (reclassified as H. hahophila), are aerobic heterotrophic micro-organisms exhibiting an extreme salt tolerance. The major organic osmoregulatory solutes of these organisms were examined u...
