    摘要: The present invention relates to (1) a transglutaminase (hereinafter referred to as TG) isolated from a Bacilli such as those of Bacillus subtilis, (2) a fraction having transglutaminase activity, and (3) a method for producing a protein, a non-proteinaceous amino acid polymer, a peptide or derivatives thereof having a crosslinked structure, by crosslinking the glutamine and lysine residues in the same with the TG or the fraction having TG activity to thereby form intermolecular or intramolecular, crosslinked .epsilon.-(.gamma.-Glu)-Lys bonds. The present invention also relates to (4) a DNA coding for a TG derived from a Bacilli such as Bacillus subtilis, (5) a vector comprising said DNA coding for the TG, (6) a cell transformed with the vector, and (7) a method for producing a Bacillus-derived transglutaminase by incubating the transformant. The crosslinked polymers produced using the Bacillus-derived TG of the present invention can be used in foods such as tofu (soybean curd), pudding, yogurt, cheese, ground fish meat, boiled fish paste, sausage and other fish and meat products and also in cosmetics, etc.

    摘要: 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.

    摘要: The present invention provides a method of 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.
