    摘要: A process for the production of L-pipecolic acid which comprises the step of reducing delta-1-piperideine-6-carboxylic acid by the use of pyrroline-5-carboxylate reductase. The delta-1-piperideine-6-carboxylic acid is obtained by the step of converting L-lysine by the use of lysine 6-aminotransferase encoded by a gene of Flavobacterium lutescens. The steps of reducing delta-1-piperideine-6-carboxylic acid and the converting of L-lysine into L-pipecolic acid by the use of lysine 6-aminotransferase are carried out by using a bacterium transformed with a gene encoding lysine 6-aminotransferase wherein such bacterium comprises pyrroline-5-carboxylate reductase encoded by a gene of Escherichia coli or a coryneform bacterium. A recombinant bacterium which can be used in this production process is also provided. Thus, the present invention can provide an efficient biological process for the production of L-pipecolic acid (or 2-piperidinecarboxylic acid).
