  • Publication number: 20150064757
    Abstract: The disclosure relates to variant carboxylic acid reductase (CAR) enzymes for the improved production of fatty alcohols in recombinant host cells.
    Type: Application
    Filed: April 2, 2013
    Publication date: March 5, 2015
    Applicant: REG Life Sciences, LLC
    Inventors: Derek L. Greenfield, Elizabeth J. Clarke, Eli S. Groban, Vikranth Arlagadda, Sungwon Lee, Xuezhi Li, Zhihao Hu
  • Publication number: 20150064782
    Abstract: The invention relates to compositions and methods, including polynucleotide sequences, amino acid sequences, recombinant host cells and recombinant host cell cultures engineered to produce fatty acid derivative compositions comprising fatty acids, fatty alcohols, fatty aldehydes, fatty esters, alkanes, terminal olefins, internal olefins or ketones. The fatty acid derivative composition is produced extracellularly with a higher titer, yield or productivity than the corresponding wild type or non-engineered host cell.
