  • NOVEL GAMMA-AMINOBUTYRATE PERMEASE VARIANT AND METHOD FOR PRODUCING ISOLEUCINE USING THE SAME
    Publication number: 20240110161
    Abstract: The present application relates to a novel ?-aminobutyrate permease variant that decreases the amount of by-products generated during the production of L-isoleucine, a polynucleotide encoding the variant, and a vector comprising the polynucleotide, a microorganism comprising the variant, polynucleotide or vector, and a method for producing L-isoleucine using the microorganism.
    Type: Application
    Filed: December 8, 2021
    Publication date: April 4, 2024
    Applicant: CJ CHEILJEDANG CORPORATION

  • NOVEL BRANCHED-CHAIN AMINO ACID AMINOTRANSFERASE VARIANT AND METHOD FOR PRODUCING ISOLEUCINE USING THE SAME
    Publication number: 20240101977
    Abstract: The present application relates to a novel branched-chain amino acid aminotransferase variant that decreases the amount of by-products generated during the production of L-isoleucine, a polynucleotide encoding the variant, and a vector comprising the polynucleotide, a microorganism comprising the variant, polynucleotide or vector, and a method for producing L-isoleucine using the microorganism.
    Type: Application
    Filed: December 3, 2021
    Publication date: March 28, 2024
    Applicant: CJ CHEILJEDANG CORPORATION
    Inventors: Heeyeong KIM, Jihyun SHIM, Kyungrim KIM, Kwang Woo LEE, Woosung CHOI
  • NOVEL ACETOHYDROXY ACID SYNTHASE VARIANT AND MICROORGANISM INCLUDING THE SAME
    Publication number: 20230203106
    Abstract: The present disclosure relates to an acetohydroxy acid synthase variant, a polynucleotide encoding the variant, a microorganism including the variant, and a method of producing L-isoleucine using the microorganism.
    Type: Application
    Filed: June 10, 2020
    Publication date: June 29, 2023
    Applicant: CJ CHEILJEDANG CORPORATION
    Inventors: Kyungrim Kim, Tae Yeon Kim, Imsang Lee, Kwang Woo Lee, Heeyeong Kim, Kwang Soo Shin
  • NOVEL OF L-THREONINE DEHYDRATASE VARIANT AND METHOD OF PRODUCING L-ISOLEUCINE USING THE SAME
    Publication number: 20230098971
    Abstract: Provided are a novel L-threonine dehydratase variant and a method of producing L-isoleucine using the same.
    Type: Application
    Filed: April 21, 2021
    Publication date: March 30, 2023
    Inventors: Kyungrim KIM, Imsang LEE, Heeyeong KIM, Kwang Woo LEE
  • MODIFIED POLYPEPTIDE OF GLUTAMINE SYNTHETASE AND METHOD OF PRODUCING L-GLUTAMINE USING THE SAME
    Publication number: 20220396815
    Abstract: The present disclosure relates to a modified polypeptide of glutamine synthetase having enhanced activity and a method of producing L-glutamine using the same. Since production of L-glutamine may be increased by using the novel modified polypeptide without a decrease in a growth rate compared to wild-type strains having glutamine synthetase activity, the modified polypeptide may be widely used for mass production of L-glutamine.
