The biocatalytic reductive amination of ketone to chiral amine is one of the most challenging reactions. Using a genome-mining approach, we found proteins catalyzing the reductive amination of ketones without a carboxylic function in the α or β position. The synthesis of (4S)-4-aminopentanoic acid (ee ≥99.5%) was achieved with the thermoactive amine dehydrogenase (AmDH) AmDH4 from Petrotoga mobilis in 88% yield. The high stability and substrate tolerance make AmDH4 a very good starting point for further discovery of reductive amination biocatalysts with an enlarged substrate range. This is the first report of wild-type enzymes with related genes having proper NAD(P)H-AmDH activity.

Herein we report the potent antimicrobial activity of α,γ-hybrid lipopeptides composed of 1:1 alternating α- and γ-amino acids. Along with their potent antimicrobial activity against various Gram-positive and Gram-negative bacteria, these hybrid lipopepti

A simple synthesis of racemic and optically active 1-azadienes derived from γ-amino esters by olefination reaction of alkyl glyoxylates and functionalized phosphonium salts or phosphine oxides is reported. Selective reduction of these 1-azadienes with hydrides yields (E)-γ-amino-α,β-unsaturated esters. A simple procedure for the preparation of saturated γ-amino acids and γ-amino esters from the previously synthesized vinylogous amino esters is also described.
