Patent number: 10202620Abstract: In certain aspects, the present invention provides methods for producing terminally hydroxylated alkenes and alkynes by contacting an unsaturated or saturated hydrocarbon substrate with a hydroxylase enzyme. Exemplary terminal hydroxylases useful for carrying out the methods of the invention exhibit strong selectivity towards one terminal carbon of a hydrocarbon substrate and include, but are not limited to, non-heme diiron alkane monooxygenases, cytochromes P450 (e.g., cytochromes P450 of the CYP52 and CYP153 family), as well as long chain alkane hydroxylases. In some embodiments, the terminally hydroxylated alkene or alkyne is further converted to a terminal alkenal. In certain embodiments, terminally hydroxylated alkenes and alkynes are useful as insect pheromones which modify insect behavior. In other embodiments, terminally hydroxylated alkenes and alkynes are useful intermediates for producing pheromones via acetylation or oxidation of the alcohol moiety.Type: GrantFiled: September 3, 2015Date of Patent: February 12, 2019Assignee: PROVIVI, INC.Inventors: Pedro Coelho, Mike M.

Patent number: 9073867Abstract: Provided herein are processes for preparing caprolactam from a starting material such as one or more of the cis,cis-, cis,trans- and trans,trans-double-bond isomers of muconamide, muconic acid ester, or muconic acid. The starting material, intermediates, and caprolactam prepared therefrom can contain carbon atoms derived from biomass containing detectable 14C content determined according to ASTM D6866 and optionally containing a 14C content up to 0.0000000001% (one part per trillion). Caprolactam so prepared can be used to make various polyamides.Type: GrantFiled: April 9, 2012Date of Patent: July 7, 2015Assignee: Amyris, Inc.Inventors: Laetitia Coudray, Vu Bui, John W.

Patent number: 8809583Abstract: A method for producing cis,trans- and trans,trans-isomers of muconate by providing cis,cis -muconate produced from a renewable carbon source through biocatalytic conversion; isomerizing cis,cis-muconate to cis,trans-muconate under reaction conditions in which substantially all of the cis,cis-muconate is isomerized to cis,trans -muconate; separating the cis,trans-muconate; and crystallizing the cis,trans-muconate. The cis,trans-isomer can be further isomerized to the trans,trans-isomer. In one example, the method includes culturing recombinant cells that express 3-dehydroshikimate dehydratase, protocatechuate decarboxylase and catechol 1,2-dioxygenase in a medium comprising the renewable carbon source and under conditions in which the renewable carbon source is converted to 3-dehydroshikimate by enzymes in the common pathway of aromatic amino acid biosynthesis of the cell, and the 3-dehydroshikimate is biocatalytically converted to cis,cis-muconate.Type: GrantFiled: January 10, 2011Date of Patent: August 19, 2014Assignee: Amyris, Inc.Inventors: Vu Bui, Man Kit Lau, Doug MacRae, Dirk Schweitzer
