Abstract:
1. A method for making a polymer in a biological system comprising providing one or more substrates selected from the group consisting of 3-hydroxybutyrate, 3-hydroxypropionate, 3-hydroxyvalerate, 4-hydroxybutyrate, 4-hydroxyvalerate, 5-hydroxyvalerate, 3-hydroxyhexanoate, 4-hydroxyhexanoate, and 6-hydroxyhexanoate, wherein the biological system is selected from the group consisting of bacteria, yeast, fungi, and plants; wherein the biological system expresses enzymes selected from the group consisting of polyhydroxyalkanoate synthase, acyl-CoA transferase, hydroxyacyl CoA transferase, and hydroxyacyl CoA synthetase such that a polymer comprising the one or more substrates accumulates, wherein the polymer is selected from the group consisting of poly(3-hydroxypropionate), poly(3-hydroxypropionate-co-5-hydroxyvalerate), poly(3-hydroxybutyrate-co-4-hydroxyvalerate), poly(4-hydroxyvalerate), and poly(5-hydroxyvalerate).
