Production method for L-cyclic amino acids

A method of producing an L-cyclic amino acid, the method comprising bringing a cyclic amino acid having a double bond at the 1-position and having the following general formula (I):

• wherein A is an alkylene chain which has a chain length of from 1 to 4 atoms, which contains or does not contain at least one hetero atom selected from the group consisting of a sulfur atom, an oxygen atom and a nitrogen atom, in the chain or at the end of the chain, and which has or does not have a substituent,
• into contact with a polypeptide shown in (A), (B) or (C) below, a microorganism or cell having the ability to produce said polypeptide or comprising said polypeptide, a processed product of the microorganism or the cell, and/or a culture liquid obtained by culturing the microorganism or the cell and comprising said polypeptide, to produce an L-cyclic amino acid having the following general formula (II):
• wherein A is the same as defined above:
• (A) a polypeptide comprising the amino acid sequence of SEQ ID NO:
• 2, 4, 6, 8, 10 or 12;
• (B) a polypeptide which comprises the amino acid sequence of SEQ ID NO:
• 2, 4, 6, 8, 10 or 12 except that 1 to 10 amino acids are deleted, conservatively substituted and/or added, and which has the ability to catalyze the reaction of the following formula (1) to produce the L-cyclic amino acid:
• wherein A is the same as defined above;
• or
• (C) a polypeptide which comprises an amino acid sequence having a sequence identity of 95% or more to the amino acid sequence of SEQ ID NO:
• 2, 4, 6, 8, 10 or 12, and which has the ability to catalyze the reaction of the formula (1) to produce the L-cyclic amino acid.
