  • Genetic constructs encoding carotenoid biosynthetic enzymes
    Patent number: 7105634
    Abstract: Genes isolated from Methylomonas sp. 16a have been determined to play a role in the carotenoid biosynthetic pathway. Specifically, crtN2 gene has the ability to produce omega-aldehyde functional groups on carotenogenic substrates, while the ald gene produced omega carboxyl functional groups. These genes will be useful for production of high levels of functionalized carotenoid compounds, especially those produced in microorganisms which metabolize single carbon substrates.

  • Genes encoding denitrification enzymes
    Patent number: 7049115
    Abstract: This invention relates to the isolation of nucleic acid fragments from Methylamons sp. that encode enzymes involved in denitrification. The enzymes arc useful in denitrification reactions and for the identification of other denitrifying bacteria. In addition, this invention also relates to the construction of chimeric genes encoding all or a substantial portion of the present genes in sense or antisense orientation, wherein the expression of the chimeric genes results in production of altered levels of the present gene products in the recombinant host.
