Don't move! The synthesis of l‐amino acids is catalysed by a hierarchical, multifunctional, heterogeneous biocatalyst. The hierarchical architecture irreversibly co‐immobilises l‐alanine dehydrogenase from B. subtilis (l‐AlaDH‐Bs) and formate dehydrogenase from C. boidinii (FDH‐Cb), with polyethyleneimine on porous agarose beads. The two enzymes and polymer colocalise across the whole microstructure

Isopropylamine is an ideal amino donor for reductive amination of carbonyl compounds by Ï-transaminase (Ï-TA) owing to its cheapness and high volatility of a ketone product. Here we developed asymmetric synthesis of unnatural amino acids via Ï-TA-catalyzed amino group transfer between α-keto acids and isopropylamine.

enzymatic system for the simultaneous synthesis of (S)-3-fluoroalanine (1a) and (R)-3-fluorolactic acid (3) with l-ALADH and l-lactate dehydrogenaseusing rac-1 and NAD+. Analysis of isolated products revealed 1a in 60% yield and 86% ee and 3 in 80% yield and over 99% ee. Compounds 1a and 3 represent chiral building blocks for the synthesis of several products with pharmacological activity. The presence
