Patents by Inventor Howard H. Chou

Howard H. Chou has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11021525
    Abstract: The present invention provides for a synthetic transcription factor (TF) comprising a first peptide capable of binding a target ligand, a second peptide capable of binding a target DNA, and a peptide linker linking the first and second peptides. The present invention also provide for a system for modulating the mutagenesis frequency of a host cell. The host cell has a mutator rate (R) which is inversely proportional to a phenotypic trait (P).
    Type: Grant
    Filed: June 10, 2015
    Date of Patent: June 1, 2021
    Assignee: The Regents of the University of California
    Inventors: Howard H. Chou, Jay D. Keasling, Sergey Zotchev

  • Patent number: 7985567
    Abstract: The invention provides for a method for producing a 5-carbon alcohol in a genetically modified host cell. In one embodiment, the method comprises culturing a genetically modified host cell which expresses a first enzyme capable of catalyzing the dephosphorylation of an isopentenyl pyrophosphate (IPP) or dimethylallyl diphosphate (DMAPP), such as a Bacillus subtilis phosphatase (YhfR), under a suitable condition so that 5-carbon alcohol is 3-methyl-2-buten-1-ol and/or 3-methyl-3-buten-1-ol is produced. Optionally, the host cell may further comprise a second enzyme capable of reducing a 3-methyl-2-buten-1-ol to 3-methyl-butan-1-ol, such as a reductase.
