CryoEM structure of the type IVa pilus secretin required for natural competence in Vibrio cholerae

In Vibrio cholerae, a type IVa pilus (T4aP) binds to exogenous DNA, and threads this DNA through the outer membrane secretin, PilQ. Here authors present the cryoEM structure of PilQ from native V. cholerae cells and design a series of mutants to reversibly regulate VcPilQ gate dynamics.
