Abstract:
The WxxxE family of bacterial effector proteins is thought to manipulate host signaling pathways by directly mimicking activated cellular GTPases. In this issue of Cell Host & Microbe, Ohlson et al. (2008) reveal that the structure of one such effector, Salmonella SifA, closely resembles that of an activator of endogenous GTPases.
