摘要:
Disclosed are a process for preparation of an optically active 7-substituted 3-(2-aminopropyl)indole compound and an intermediate therefor. In the above preparation process, 7-substituted indole is reacted with L- or DL-serine in the presence of a tryptophan-synthesizing enzyme originating in microorganisms to form corresponding 7-substituted L-tryptophan, and it is subjected, if necessary, to reduction, protection, exchange and elimination.
摘要:
A process for producing L-2-aminoadipic acid, which comprises converting an aminomethyl group of L-lysine into a carboxyl group by use of a culture of a microorganism of the genus Flavobacterium. By this process, L-2-aminoadipic acid can be obtained directly from L-lysine in a high yield. This process is a microbial method which is effective for the mass production.
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. 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).
摘要:
Provided are an isolated gene capable of participating in the production of L-homoglutamic acid, and a production system of L-homoglutamic acid by using this gene. The gene is derived from the genome of Flavobacterium lutescens .
