Cylindrocyclophane Biosynthesis Involves Functionalization of an Unactivated Carbon Center
摘要:
The cylindrocyclophanes are a family of natural products that share a remarkable paracyclophane carbon scaffold. Using genome sequencing and bioinformatic analyses; we have discovered a biosynthetic gene cluster involved in the assembly of cylindrocyclophane F. Through a combination of in vitro enzyme characterization and feeding Studies, We Confirm the connection between this gene cluster and cylindrocyclophane production, elucidate the chemical events involved in initiating and terminating an unusual type I polyketide synthase assembly line, and discover that macrocycle assembly involves functionalization of an unactivated carbon center.

Protein prenylation is a type of post-translational modification that aids certain proteins in localizing to the plasma member where they activate cell signaling. To better understand the isoprenoid requirements and differences of FTase and GGTase-I, a series of saturated geranylgeranyl diphosphate analogs were synthesized and screened against both mammalian FTase and GGTase-I.
