Cryogenic Electron Microscopy Reveals Conformational Dynamics and Catalytic Mechanisms of Human Fatty Acid Synthase in De Novo Lipid Biosynthesis
Abstract: Fatty acid synthase (FASN) is a multifunctional homodimeric enzyme central to de novo fatty acid synthesis in mammals. Recent cryogenic electron microscopy (cryo-EM) studies have illuminated the structural basis of FASN catalysis, revealing multiple conformational states throughout the synthesis cycle. These findings show that the acyl carrier protein (ACP) domain dynamically shuttles substrates between spatially separated active sites, while the condensing and modifying regions remain structurally stable. In contrast to …
