标题:Metabolic engineering of polyhydroxyalkanoate monomer synthases
发明人：SHERMAN DAVID H; WILLIAMS MARK D; XUE YONGQUAN
权利人:UNIV MINNESOTA
摘要:A novel pathway for the synthesis of polyhydroxyalkanoate is provided. A method of synthesizing a recombinant polyhydroxyalkanoate monomer synthase is also provided. These recombinant polyhydroxyalknoate synthases are derived from multifunctional fatty acid synthases or polyketide synthases and generate hydroxyacyl acids capable of polymerization by a polyhydroxyalknoate synthase.

摘要:Method for the synthesis of a compound of formula H(OCH[CH 3 ]CH 2 C[O]) 3 —O-A-O—R wherein A is the residue of 1,3-butandiol and R is H or H(OCH[CH 3 ]CH 2 C[O] 3 —. The method comprises reacting a cyclic oligomer of (R)-3-hydroxybutyrate consisting of (R)-3-hydroxybutyrate moieties with a 1,3-butandiol in an organic solvent in the presence of Candida antarctica lipase type B in a furan or pyran solvent.

摘要:PHB-deficient Sphingomonas strains having improved sphingan yield are provided. Certain of the Sphingomonas strains are diutan-producing strains that exhibit a dramatic improvement in productivity and yield due to a combination of certain genetic modifications that affect PHB and sphingan synthesis. Moreover, the sphingans produced from such strains have superior characteristics including improved filterability, clarity, and improved rheology-modifying characteristics. The sphingans provided are, thus, highly desirable in a variety of commercial and industrial uses, including personal care items, cement applications, and oilfield applications.
