A new paper from the Strynadka lab uses cryo-EM to solve the structure of the bacterial protein EscV. EscV is a key protein in controlling the export of substrates through a macromolecular ‘syringe’ known as the Type III secretion system, which bacteria use to transfer proteins, including toxins, directly into host cells.
The structure of EscV, a protein involved in bacterial secretion, has been solved by researchers at UBC.
