  • Publication number: 20240084340
    Abstract: Nucleic acids and cells comprising a methyltransferase gene and/or a reductase gene are disclosed. These nucleic acids and cells may be used to produce branched (methyl)lipids, such as 10-methylstearate.
    Type: Application
    Filed: July 27, 2023
    Publication date: March 14, 2024
    Inventors: Arthur J. Shaw, Hannah Blitzblau, Donald V. Crabtree
  • Publication number: 20220340939
    Abstract: Disclosed herein are cells, nucleic acids, and proteins that can be used to produce branched (methyl)lipids, such as 10-methylstearic acids, and compositions that include such lipids. Cells disclosed herein comprise methyltransferase and/or reductase genes from bacteria of the class Gammaproteobacteria, which encode enzymes capable of catalyzing the production of branched (methyl)lipids from unbranched, unsaturated lipids. Saturated branched (methyl)lipids produced using embodiments of the present invention have favorable low-temperature fluidity and favorable oxidative stability, which are desirable properties for lubricants and specialty fluids.
    Type: Application
    Filed: January 30, 2022
