Method for the poduction of cyclic molecules

The invention at hand describes a method for the cyclization of peptides and proteins in which linear thioesters serve as substrates. The cyclization is catalyzed by thioesterase domains of NRPS or PKS cyclases. The substrates according to the present invention are composed of one linear peptide on which a charge-stabilized aromatic, heteroaromatic or araliphatic leaving group is bound. These substrates lead to higher yields and reaction rates than linear peptides able to be cyclized with methods known so far and, furthermore, allow the cyclization of such peptides which were previously not able to be cyclized.

Biosynthesis of polyketides

InactiveUS20190002848A1Increase diversityWide-ranging product diversityAcyltransferasesFermentationClaisen condensationPolyketide biosynthesis
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.
