Ping, pong, and freeze: Structural insights into the inhibition of ceramide synthase by Fumonisin B1
Fumonisin B1 (FB1) targets sphingolipid biosynthesis, inhibiting ceramide synthases. In this issue of Structure, Zhang et al.1 determined the cryoelectron microscopic structures of yeast ceramide synthase in complex with FB1 and its acylated derivative, acyl-FB1, revealing a two-step “ping-pong” mechanism for the N-acylation of FB1 and how it inhibits ceramide synthase.
期刊介绍:
Structure aims to publish papers of exceptional interest in the field of structural biology. The journal strives to be essential reading for structural biologists, as well as biologists and biochemists that are interested in macromolecular structure and function. Structure strongly encourages the submission of manuscripts that present structural and molecular insights into biological function and mechanism. Other reports that address fundamental questions in structural biology, such as structure-based examinations of protein evolution, folding, and/or design, will also be considered. We will consider the application of any method, experimental or computational, at high or low resolution, to conduct structural investigations, as long as the method is appropriate for the biological, functional, and mechanistic question(s) being addressed. Likewise, reports describing single-molecule analysis of biological mechanisms are welcome.
In general, the editors encourage submission of experimental structural studies that are enriched by an analysis of structure-activity relationships and will not consider studies that solely report structural information unless the structure or analysis is of exceptional and broad interest. Studies reporting only homology models, de novo models, or molecular dynamics simulations are also discouraged unless the models are informed by or validated by novel experimental data; rationalization of a large body of existing experimental evidence and making testable predictions based on a model or simulation is often not considered sufficient.
