DNA and recombinant DNA that encode a peptide-forming enzyme, a method for producing a peptide-forming enzyme, and a method for producing a dipeptide are disclosed. A method for producing a dipeptide includes producing a dipeptide from a carboxy component and an amine component by using a culture of a microbe belonging to the genus Sphingobacterium and having the ability to form the dipeptide from the carboxy component and the amine component, a microbial cell separated from the culture, treated microbial cell product of the microbe or a peptide-forming enzyme derived from the microbe.

A method is disclosed that allows the production of peptides having three or more amino acid residues easily, inexpensively and at high yield without going through a complex synthesis method. A novel enzyme that efficiently produces a peptide from bacteria belonging to the genus
Empedobacter
or the genus
Sphingobacterium
is provided. The enzyme acts on a carboxy component and an amine component to form peptides having three or more amino acid residues by acting on a carboxy component and an amine component.

The present invention relates to a novel enzyme that allows peptide to be produced easily, inexpensively and at high yield without going through a complex synthesis method. More particularly, the present invention provides a novel enzyme that catalyzes a peptide-producing reaction from a carboxy component and an amine component, a microbe that produces the enzyme, and a method for inexpensive production of peptides using this enzyme or microbe. The novel enzyme that efficiently produces peptide was discovered from a newly discovered microbe belonging to the genus
Empedobacter,
and a method was found that allows peptides to be produced inexpensively and easily.
The present invention provides a method for producing a dipeptide from starting materials that are available at low costs through a route industrially advantageous and simple. Dipeptides are produced from amino acid esters and amino acids by using a culture of a microbe having an ability to produce a dipeptide from an amino acid ester and an amino acid, microbial cells separated from the culture, or treated microbial cell product.
