    • This disclosure generally relates to the use of microorganisms to make various functionalized polyketides through polyketoacyl-CoA thiolase-catalyzed non-decarboxylative condensation reactions instead of decarboxylative reactions catalyzed by polyketide synthases. Native or engineered polyketoacyl-CoA thiolases catalyze the non-decarboxylative Claisen condensation in an iterative manner (i.e. multiple rounds) between two either unsubstituted or functionalized ketoacyl-CoAs (and polyketoacyl-CoAs) serving as the primers and acyl- CoAs serving as the extender unit to generate (and elongate) polyketoacyl-CoAs. Before the next round of polyketoacyl-CoA thiolase reaction, the β-keto group of the polyketide chain of polyketoacyl-CoA can be reduced and modified step-wise by 3-OH-polyketoacyl-CoA dehydrogenase or polyketoenoyl-CoA hydratase or polyketoenoyl-CoA reductase. Dehydrogenase converts the β-keto group to β-hydroxy group. Hydratase converts the β- hydroxy group to α-β-double-bond. Reductase converts the α-β-double-bond to single bond. Spontaneous or thioesterase catalyzed termination reaction terminates the elongation of polyketide chain of polyketoacyl-CoA at any point through CoA removal and spontaneous reactions rearrange the structure, generating the final functional polyketide products.
    • 本公开一般涉及微生物通过聚酮酰辅酶A硫解酶催化的非脱羧缩合反应而不是由聚酮化合物合酶催化的脱羧反应来制备各种官能化聚酮化合物的用途。 天然或工程改造的聚酮酰基-CoA硫解酶以反复方式(即多轮)在作为引物的未取代的或官能化的酮酰基-CoA(和聚酮酰基-CoA)和充当扩展剂的酰基-CoA之间催化非脱羧Claisen缩合 单元以产生(并拉长)聚酮酰辅酶A。 在下一轮聚酮酰辅酶A硫解酶反应之前,聚酮酰辅酶A的聚酮化合物链的β-酮基可被还原并通过3-OH-聚酮酰辅酶A脱氢酶或多酮酰辅酶A水合酶或多酮酰辅酶A 还原酶。 脱氢酶将β-酮基转化为β-羟基。 水合酶将β-羟基转化为α-β-双键。 还原酶将α-β-双键转化为单键。 自发或硫酯酶催化的终止反应通过CoA去除终止聚酮酰辅酶A的聚酮化合物链的延长,并且自发反应重新排列结构,产生最终的功能性聚酮化合物产物。

    • In some embodiments, the present disclosure pertains to methods of producing a graphene hybrid material by exposing a graphene precursor material to a laser source to form a laser-induced graphene, where the laser-induced graphene is derived from the graphene precursor material. The methods of the present disclosure also include a step of associating a pseudocapacitive material (e.g., a conducting polymer or a metal oxide) with the laser-induced graphene to form the graphene hybrid material. The formed graphene hybrid material can become embedded with or separated from the graphene precursor material. The graphene hybrid materials can also be utilized as components of an electronic device, such as electrodes in a microsupercapacitor. Additional embodiments of the present disclosure pertain to the aforementioned graphene hybrid materials and electronic devices.
