Method for manufacturing cis-5-hydroxy-L-pipecolic acid

1. A method for producing cis-5-hydroxy-L-pipecolic acid, the method comprising allowing a 2-oxoglutarate-dependent L-pipecolic acid hydroxylase, a microorganism or cell that produces the enzyme, a processed product of the microorganism or cell having the enzyme, and/or a culture liquid comprising the enzyme and obtained by culturing the microorganism or cell, to act on L-pipecolic acid to generate cis-5-hydroxy-L-pipecolic acid,

wherein the 2-oxoglutarate-dependent L-pipecolic acid hydroxylase comprises:

(A) a polypeptide comprising the amino acid sequence of SEQ ID NO: 4 or 11;

(B) a polypeptide comprising the amino acid sequence of SEQ ID NO: 4 or 11 except that 1 to 10 amino acids are deleted, substituted, and/or added, wherein said polypeptide has 2-oxoglutarate-dependent L-pipecolic acid hydroxylase activity; or

(C) a polypeptide comprising an amino acid sequence with an identity of not less than 90% to the amino acid sequence of SEQ ID NO: 4 or 11, wherein said polypeptide has 2-oxoglutarate-dependent L-pipecolic acid hydroxylase activity.

2. The method for producing cis-5-hydroxy-L-pipecolic acid according to claim 1 , wherein DNA encoding the 2-oxoglutarate-dependent L-pipecolic acid hydroxylase comprises:

(a) DNA comprising the nucleotide sequence of SEQ ID NO: 1 or 10;

(b) DNA comprising the nucleotide sequence of SEQ ID NO: 1 or 10 except that 1 to 30 nucleotides are substituted, deleted, and/or added, wherein said DNA encodes a polypeptide having 2-oxoglutarate-dependent L-pipecolic acid hydroxylase activity; or

(c) DNA which hybridizes with the full-length complementary strand of the polynucleotide of SEQ ID NO: 1 or 10 under stringent conditions, wherein the conditions comprise a hybridization at 65° C. in the presence of 0.7 mol/L to 1.0 mol/L sodium chloride aqueous solution and a washing under a temperature condition of 65° C. by using one solution with an SSC concentration ranging from 0.1 to 2×SSC (the composition of 1×SSC: 150 mmol/L sodium chloride aqueous solution, 15 mmol/L sodium citrate aqueous solution), wherein said DNA encodes a polypeptide having 2-oxoglutarate-dependent L-pipecolic acid hydroxylase activity.

3. The method for producing cis-5-hydroxy-L-pipecolic acid according to claim 1 , wherein the 2-oxoglutarate-dependent L-pipecolic acid hydroxylase, the microorganism or cell that produces the enzyme, the processed product of the microorganism or cell having the enzyme, and/or the culture liquid comprising the enzyme and obtained by culturing the microorganism or cell is/are allowed to act on said L-pipecolic acid in the presence of 2-oxoglutaric acid and a ferrous ion.

4. The method for producing cis-5-hydroxy-L-pipecolic acid according to claim 2 , wherein the 2-oxoglutarate-dependent L-pipecolic acid hydroxylase, the microorganism or cell that produces the enzyme, the processed product of the microorganism or cell having the enzyme, and/or the culture liquid comprising the enzyme and obtained by culturing the microorganism or cell is/are allowed to act on said L-pipecolic acid in the presence of 2-oxoglutaric acid and a ferrous ion.

5. A 2-oxoglutarate-dependent L-pipecolic acid hydroxylase protein having an activity to act on L-pipecolic acid to generate cis-5-hydroxy-L-pipecolic acid, wherein said 2-oxoglutarate-dependent L-pipecolic acid hydroxylase protein comprises:

a polypeptide comprising the amino acid sequence of SEQ ID NO: 4 or 11 except that 1-10 amino acids are substituted and/or added, wherein said polypeptide has 2-oxoglutarate-dependent L-pipecolic acid hydroxylase activity.
