Publication number: 20140248673Abstract: This document describes biochemical pathways for producing pimelic acid, 7-hydroxyheptanoic acid, 7-aminoheptanoic acid, heptamethylenediamine or 1,7-heptanediol by forming two terminal functional groups, comprised of carboxyl, amine or hydroxyl group, in a C7 aliphatic backbone substrate. These pathways, metabolic engineering and cultivation strategies described herein rely on the CoA-dependent elongation enzymes or analog enzymes associated with the carbon storage pathways from polyhydroxyalkanoate accumulating bacteria.Type: ApplicationFiled: December 13, 2013Publication date: September 4, 2014Applicant: INVISTA North America S.á r.I.Inventors: Adriana Leonora Botes, Alex Van Eck Conradie

Publication number: 20140242655Abstract: Embodiments of the present invention relate to methods for the biosynthesis of di- or trifunctional C7 alkanes in the presence of isolated enzymes or in the presence of a recombinant host cell expressing those enzymes. The di- or trifunctional C7 alkanes are useful as intermediates in the production of nylon-7, nylon-7,x, nylon-x,7, and polyesters.Type: ApplicationFiled: June 29, 2012Publication date: August 28, 2014Applicant: INVISTA TECHNOLOGIES S.A R.L.Inventors: Paul S.

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
