  • 4-amino cinnamic acid production method using enzyme
    Patent number: 10053716
    Abstract: This 4-amino cinnamic acid production method using the enzyme ammonia lyase can efficiently convert 4-amino phenylalanine into 4-amino cinnamic acid. This 4-amino cinnamic acid production method is characterized by converting 4-amino phenylalanine into 4-amino cinnamic acid by using phenylalanine ammonia-lyase, which comprises the amino acid sequence represented in sequence number 2 derived from the Rhodotorula glutinis yeast.

  • Method for producing aniline derivative by fermentation from carbon source
    Patent number: 9920343
    Abstract: Provided is a method for producing an aniline derivative by fermentation from a carbon source such as glucose. The method comprises the following steps: production of microorganisms capable of producing 1.8 g/L or more of 4-aminophenylalanine (4APhe) under prescribed culture conditions by introducing at least three exogenous genes into microorganisms having the ability to biosynthesize 4-aminophenylpyruvic acid from chorismic acid; and production of at least one aniline derivative selected from the group consisting of 4-aminophenylalanine (4APhe), 4-aminocinnamic acid (4ACA), 2-(4-aminophenyl)aldehyde, 4-aminophenylacetic acid, and 4-aminophenethylethanol (4APE) by bringing these microorganisms into contact with a carbon source under conditions suited to the growth and/or maintenance of these microorganisms.
