The structure of beta-ketoacyl synthase is similar to that of the thiolase family (Pfam:PF00108) and also chalcone synthase. The active site of beta-ketoacyl synthase is located between the N and C-terminal domains. The N-terminal domain contains most of the structures involved in dimer formation and also the active site cysteine [1].
This entry represents a linker domain found in polyketide synthases, which connects the N-terminal domains with the B-domain as described in RhiE [1-3].

This entry represents the RhiE branching domain, which is part of a non-canonical polyketide synthase (PKS) module found in the endofungal bacterium Burkholderia rhizoxinica. Unlike typical PKS modules, RhiE catalyzes a Michael-type acetyl addition to generate a branch in the carbon chain, expanding the biosynthetic scope of polyketide biosynthesis. The module consists of a ketosynthase domain, an acyl carrier protein domain, and a cryptic branching ('B') domain in between, featuring a double hot dog (DHD) fold that is structurally homologous to the product template domain of a fungal PKS. The RhiE B domain alone is not sufficient to catalyze the Michael addition, and mutagenesis experiments revealed a crucial role of the ketosynthase domain in branching the carbon chain.
