Congratulations to the Strynadka Lab on their paper published in Nature Communications! Researchers used cryo-EM to determine a high resolution structure of the Type III Secretion System, and processed the data to obtain near atomic resolution structures of several components which make up this assembly.
A near atomic structure of the type III secretion system has allowed researchers from the Strynadka to create a model for the proposed gating mechanism of secretin which leads to needle assembly.
