Enzymatic synthesis of L-pipecolic acid by Delta1-piperideine-2-carboxylate reductase from Pseudomonas putida.

ABSTRACT

L-Pipecolic acid is a chiral pharmaceutical intermediate. An enzymatic system for the synthesis of L-pipecolic acid from L-lysine by commercial L-lysine alpha-oxidase from Trichoderma viride and an extract of recombinant Escherichia coli cells coexpressing Delta1-piperideine-2-carboxylate reductase from Pseudomonas putida and glucose dehydrogenase from Bacillus subtilis is described. A laboratory-scale process provided 27 g/l of L-pipecolic acid in 99.7% e.e.
