Asymmetric synthesis of a high added value chiral amine using immobilized ω-transaminases
Chiral N-heterocyclic molecules and in particular compounds with an amino functional group such as 3-aminopiperidine are valuable intermediates for the production of a large number of bioactive compounds with pharmacological properties.

Are emerging deep eutectic solvents (DES) relevant for lipase-catalyzed lipophilizations? [PDF]
With the recent interest on green chemistry, the scientists have focused on developing new and more efficiient solvents to carry out enzymatic-catalyzed reactions with emphasis on reduced costs, risks and toxicity while improving biodegradability.

Stereoelectronic effects in the reaction of aromatic substrates catalysed by Halomonas elongata transaminase and its mutants [PDF]
A transaminase from Halomonas elongata and four mutants generated by an in silico-based design, were recombinantly produced in E. coli, purified and applied to the amination of mono-substituted aromatic carbonyl-derivatives.
