  • Process for producing transglutaminase by microorganism
    Patent number: 6472182
    Abstract: The present invention provides a process for producing a transglutaminase, which comprises culturing microorganisms of any of the genus Micrococcus, Clostridium, Torulopsis, Rhizopus and Monascus in a medium to produce the intended transglutaminase in the medium or in the cells of the microorganisms and then isolating the transglutaminase, and a process for producing a gelled proten with the thus-obtained transglutaminase. According to the process of the present invention, transglutaminase can be rapidly produced at a low cost.

  • Bacillus-derived transglutaminase
    Patent number: 5948662
    Abstract: A method for processing a protein, a non-proteinaceous amino acid polymer, or a non-proteinaceous amino acid polymer, or a peptide or derivatives thereof having a crosslinked structure, which entails contacting glutamine and lysine residues in a protein, a non-proteinaceous amino acid polymer, a peptide or derivatives thereof with a transglutaminase obtained from Bacillus subtilus to form intermolecular or intramolecular, crosslinked .epsilon.(.delta.-Glu)-Lys bonds between or in the molecules of the protein, non-proteinaceous amino acid polymer, peptide or derivatives thereof, wherein the transglutaminase has the physicochemical properties described herein.

  • Bacillus-derived transglutaminase
    Patent number: 5731183
    Abstract: 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.
