WebThe cylindrocyclophanes are a family of natural products that contain an unusual [7.7]paracyclophane core scaffold. Based on the previous work on the cylindrocyclophanes, their biosynthesis was predicted to involve an extraordinary C–C bond-formation. WebAlkylation of aromatic rings with alkyl halides is an important transformation in organic synthesis, yet an enzymatic equivalent is unknown. Here, we report that cylindrocyclophane biosynthesis in Cylindrospermum licheniforme ATCC 29412 involves chlorination of an unactivated carbon center by a novel halogenase, followed by a …

Webterminated by a separate enzyme in trans. In cylindrocyclophane biosynthesis, the type I modular PKS assembly line is terminated by a freestanding type III PKS (CylI). Unexpectedly, the final module of the type I PKS (CylH) also possesses a C-terminal TE domain. Unlike typical type I PKSs, the CylH TE domain WebCylindrocyclophane biosynthesis, however, is unique in possessing both a freestanding terminating enzyme and a C-terminal TE domain on the final module of its type I modular PKS assembly line (CylH). This is surprising, as termination via a type III PKS should not require a type I TE domain. tallulah and stella estate sales
