A glycine-rich PE_PGRS protein governs mycobacterial actin-based motility
Abstract
Mycobacterium marinum, a close relative of Mycobacterium tuberculosis, polymerizes host actin at the bacterial surface to drive intracellular movement and cell-to-cell spread during infection. Here, Hill & Welch identify an M. marinum surface protein that binds to and activates the host protein NWASP to stimulate actin polymerization and drive bacterial actin-based motility.
